Instance Method Details
#associate_faces(params = {}) ⇒ Types::AssociateFacesResponse
Associates one or more faces with an existing UserID. Takes an array
of FaceIds
. Each FaceId
that are present in the FaceIds
list is
associated with the provided UserID. The maximum number of total
FaceIds
per UserID is 100.
The UserMatchThreshold
parameter specifies the minimum user match
confidence required for the face to be associated with a UserID that
has at least one FaceID
already associated. This ensures that the
FaceIds
are associated with the right UserID. The value ranges from
0-100 and default value is 75.
If successful, an array of AssociatedFace
objects containing the
associated FaceIds
is returned. If a given face is already
associated with the given UserID
, it will be ignored and will not be
returned in the response. If a given face is already associated to a
different UserID
, isn't found in the collection, doesn’t meet the
UserMatchThreshold
, or there are already 100 faces associated with
the UserID
, it will be returned as part of an array of
UnsuccessfulFaceAssociations.
The UserStatus
reflects the status of an operation which updates a
UserID representation with a list of given faces. The UserStatus
can
be:
ACTIVE - All associations or disassociations of FaceID(s) for a UserID are complete.
CREATED - A UserID has been created, but has no FaceID(s) associated with it.
UPDATING - A UserID is being updated and there are current associations or disassociations of FaceID(s) taking place.

#compare_faces(params = {}) ⇒ Types::CompareFacesResponse
Compares a face in the source input image with each of the 100 largest faces detected in the target input image.
If the source image contains multiple faces, the service detects the largest face and compares it with each face detected in the target image.
CompareFaces
to
make a decision that impacts an individual's rights, privacy, or
access to services, we recommend that you pass the result to a human
for review and further validation before taking action.
You pass the input and target images either as base64-encoded image bytes or as references to images in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes isn't supported. The image must be formatted as a PNG or JPEG file.
In response, the operation returns an array of face matches ordered by similarity score in descending order. For each face match, the response provides a bounding box of the face, facial landmarks, pose details (pitch, roll, and yaw), quality (brightness and sharpness), and confidence value (indicating the level of confidence that the bounding box contains a face). The response also provides a similarity score, which indicates how closely the faces match.
SimilarityThreshold
parameter.
CompareFaces
also returns an array of faces that don't match the
source image. For each face, it returns a bounding box, confidence
value, landmarks, pose details, and quality. The response also returns
information about the face in the source image, including the bounding
box of the face and confidence value.
The QualityFilter
input parameter allows you to filter out detected
faces that don’t meet a required quality bar. The quality bar is based
on a variety of common use cases. Use QualityFilter
to set the
quality bar by specifying LOW
, MEDIUM
, or HIGH
. If you do not
want to filter detected faces, specify NONE
. The default value is
NONE
.
If the image doesn't contain Exif metadata, CompareFaces
returns
orientation information for the source and target images. Use these
values to display the images with the correct image orientation.
If no faces are detected in the source or target images,
CompareFaces
returns an InvalidParameterException
error.
For an example, see Comparing Faces in Images in the Amazon Rekognition Developer Guide.
This operation requires permissions to perform the
rekognition:CompareFaces
action.

#copy_project_version(params = {}) ⇒ Types::CopyProjectVersionResponse
Copies a version of an Amazon Rekognition Custom Labels model from a source project to a destination project. The source and destination projects can be in different AWS accounts but must be in the same AWS Region. You can't copy a model to another AWS service.
To copy a model version to a different AWS account, you need to create a resource-based policy known as a project policy. You attach the project policy to the source project by calling PutProjectPolicy. The project policy gives permission to copy the model version from a trusting AWS account to a trusted account.
For more information creating and attaching a project policy, see Attaching a project policy (SDK) in the Amazon Rekognition Custom Labels Developer Guide.
If you are copying a model version to a project in the same AWS account, you don't need to create a project policy.
To copy a model, the destination project, source project, and source model version must already exist.
Copying a model version takes a while to complete. To get the current
status, call DescribeProjectVersions and check the value of Status
in the ProjectVersionDescription object. The copy operation has
finished when the value of Status
is COPYING_COMPLETED
.
This operation requires permissions to perform the
rekognition:CopyProjectVersion
action.

#create_collection(params = {}) ⇒ Types::CreateCollectionResponse
Creates a collection in an AWS Region. You can add faces to the collection using the IndexFaces operation.
For example, you might create collections, one for each of your
application users. A user can then index faces using the IndexFaces
operation and persist results in a specific collection. Then, a user
can search the collection for faces in the user-specific container.
When you create a collection, it is associated with the latest version of the face model version.
This operation requires permissions to perform the
rekognition:CreateCollection
action. If you want to tag your
collection, you also require permission to perform the
rekognition:TagResource
operation.

#create_dataset(params = {}) ⇒ Types::CreateDatasetResponse
Creates a new Amazon Rekognition Custom Labels dataset. You can create a dataset by using an Amazon Sagemaker format manifest file or by copying an existing Amazon Rekognition Custom Labels dataset.
To create a training dataset for a project, specify TRAIN
for the
value of DatasetType
. To create the test dataset for a project,
specify TEST
for the value of DatasetType
.
The response from CreateDataset
is the Amazon Resource Name (ARN)
for the dataset. Creating a dataset takes a while to complete. Use
DescribeDataset to check the current status. The dataset created
successfully if the value of Status
is CREATE_COMPLETE
.
To check if any non-terminal errors occurred, call ListDatasetEntries
and check for the presence of errors
lists in the JSON Lines.
Dataset creation fails if a terminal error occurs (Status
=
CREATE_FAILED
). Currently, you can't access the terminal error
information.
For more information, see Creating dataset in the Amazon Rekognition Custom Labels Developer Guide.
This operation requires permissions to perform the
rekognition:CreateDataset
action. If you want to copy an existing
dataset, you also require permission to perform the
rekognition:ListDatasetEntries
action.

#create_face_liveness_session(params = {}) ⇒ Types::CreateFaceLivenessSessionResponse
This API operation initiates a Face Liveness session. It returns a
SessionId
, which you can use to start streaming Face Liveness video
and get the results for a Face Liveness session.
You can use the OutputConfig
option in the Settings parameter to
provide an Amazon S3 bucket location. The Amazon S3 bucket stores
reference images and audit images. If no Amazon S3 bucket is defined,
raw bytes are sent instead.
You can use AuditImagesLimit
to limit the number of audit images
returned when GetFaceLivenessSessionResults
is called. This number
is between 0 and 4. By default, it is set to 0. The limit is best
effort and based on the duration of the selfie-video.

#create_project(params = {}) ⇒ Types::CreateProjectResponse
Creates a new Amazon Rekognition project. A project is a group of
resources (datasets, model versions) that you use to create and manage
a Amazon Rekognition Custom Labels Model or custom adapter. You can
specify a feature to create the project with, if no feature is
specified then Custom Labels is used by default. For adapters, you can
also choose whether or not to have the project auto update by using
the AutoUpdate argument. This operation requires permissions to
perform the rekognition:CreateProject
action.

#create_project_version(params = {}) ⇒ Types::CreateProjectVersionResponse
Creates a new version of Amazon Rekognition project (like a Custom
Labels model or a custom adapter) and begins training. Models and
adapters are managed as part of a Rekognition project. The response
from CreateProjectVersion
is an Amazon Resource Name (ARN) for the
project version.
The FeatureConfig operation argument allows you to configure specific
model or adapter settings. You can provide a description to the
project version by using the VersionDescription argment. Training can
take a while to complete. You can get the current status by calling
DescribeProjectVersions. Training completed successfully if the value
of the Status
field is TRAINING_COMPLETED
. Once training has
successfully completed, call DescribeProjectVersions to get the
training results and evaluate the model.
This operation requires permissions to perform the
rekognition:CreateProjectVersion
action.
You can train a model in a project that doesn't have associated
datasets by specifying manifest files in the TrainingData
and
TestingData
fields.
If you open the console after training a model with manifest files, Amazon Rekognition Custom Labels creates the datasets for you using the most recent manifest files. You can no longer train a model version for the project by specifying manifest files.
Instead of training with a project without associated datasets, we recommend that you use the manifest files to create training and test datasets for the project.

#create_stream_processor(params = {}) ⇒ Types::CreateStreamProcessorResponse
Creates an Amazon Rekognition stream processor that you can use to detect and recognize faces or to detect labels in a streaming video.
Amazon Rekognition Video is a consumer of live video from Amazon Kinesis Video Streams. There are two different settings for stream processors in Amazon Rekognition: detecting faces and detecting labels.
If you are creating a stream processor for detecting faces, you provide as input a Kinesis video stream (
Input
) and a Kinesis data stream (Output
) stream for receiving the output. You must use theFaceSearch
option inSettings
, specifying the collection that contains the faces you want to recognize. After you have finished analyzing a streaming video, use StopStreamProcessor to stop processing.If you are creating a stream processor to detect labels, you provide as input a Kinesis video stream (
Input
), Amazon S3 bucket information (Output
), and an Amazon SNS topic ARN (NotificationChannel
). You can also provide a KMS key ID to encrypt the data sent to your Amazon S3 bucket. You specify what you want to detect by using theConnectedHome
option in settings, and selecting one of the following:PERSON
,PET
,PACKAGE
,ALL
You can also specify where in the frame you want Amazon Rekognition to monitor withRegionsOfInterest
. When you run the StartStreamProcessor operation on a label detection stream processor, you input start and stop information to determine the length of the processing time.
Use Name
to assign an identifier for the stream processor. You use
Name
to manage the stream processor. For example, you can start
processing the source video by calling StartStreamProcessor with the
Name
field.
This operation requires permissions to perform the
rekognition:CreateStreamProcessor
action. If you want to tag your
stream processor, you also require permission to perform the
rekognition:TagResource
operation.

#create_user(params = {}) ⇒ Struct
Creates a new User within a collection specified by CollectionId
.
Takes UserId
as a parameter, which is a user provided ID which
should be unique within the collection. The provided UserId
will
alias the system generated UUID to make the UserId
more user
friendly.
Uses a ClientToken
, an idempotency token that ensures a call to
CreateUser
completes only once. If the value is not supplied, the
AWS SDK generates an idempotency token for the requests. This prevents
retries after a network error results from making multiple
CreateUser
calls.

#detect_custom_labels(params = {}) ⇒ Types::DetectCustomLabelsResponse
Detects custom labels in a supplied image by using an Amazon Rekognition Custom Labels model.
You specify which version of a model version to use by using the
ProjectVersionArn
input parameter.
You pass the input image as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.
For each object that the model version detects on an image, the API
returns a (CustomLabel
) object in an array (CustomLabels
). Each
CustomLabel
object provides the label name (Name
), the level of
confidence that the image contains the object (Confidence
), and
object location information, if it exists, for the label on the image
(Geometry
). Note that for the DetectCustomLabelsLabels
operation,
Polygons
are not returned in the Geometry
section of the response.
To filter labels that are returned, specify a value for
MinConfidence
. DetectCustomLabelsLabels
only returns labels with a
confidence that's higher than the specified value. The value of
MinConfidence
maps to the assumed threshold values created during
training. For more information, see Assumed threshold in the Amazon
Rekognition Custom Labels Developer Guide. Amazon Rekognition Custom
Labels metrics expresses an assumed threshold as a floating point
value between 0-1. The range of MinConfidence
normalizes the
threshold value to a percentage value (0-100). Confidence responses
from DetectCustomLabels
are also returned as a percentage. You can
use MinConfidence
to change the precision and recall or your model.
For more information, see Analyzing an image in the Amazon
Rekognition Custom Labels Developer Guide.
If you don't specify a value for MinConfidence
,
DetectCustomLabels
returns labels based on the assumed threshold of
each label.
This is a stateless API operation. That is, the operation does not persist any data.
This operation requires permissions to perform the
rekognition:DetectCustomLabels
action.
For more information, see Analyzing an image in the Amazon Rekognition Custom Labels Developer Guide.

#detect_faces(params = {}) ⇒ Types::DetectFacesResponse
Detects faces within an image that is provided as input.
DetectFaces
detects the 100 largest faces in the image. For each
face detected, the operation returns face details. These details
include a bounding box of the face, a confidence value (that the
bounding box contains a face), and a fixed set of attributes such as
facial landmarks (for example, coordinates of eye and mouth), pose,
presence of facial occlusion, and so on.
The face-detection algorithm is most effective on frontal faces. For non-frontal or obscured faces, the algorithm might not detect the faces or might detect faces with lower confidence.
You pass the input image either as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.
This operation requires permissions to perform the
rekognition:DetectFaces
action.

#detect_labels(params = {}) ⇒ Types::DetectLabelsResponse
Detects instances of real-world entities within an image (JPEG or PNG) provided as input. This includes objects like flower, tree, and table; events like wedding, graduation, and birthday party; and concepts like landscape, evening, and nature.
For an example, see Analyzing images stored in an Amazon S3 bucket in the Amazon Rekognition Developer Guide.
You pass the input image as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.
Optional Parameters
You can specify one or both of the GENERAL_LABELS
and
IMAGE_PROPERTIES
feature types when calling the DetectLabels API.
Including GENERAL_LABELS
will ensure the response includes the
labels detected in the input image, while including IMAGE_PROPERTIES
will ensure the response includes information about the image quality
and color.
When using GENERAL_LABELS
and/or IMAGE_PROPERTIES
you can provide
filtering criteria to the Settings parameter. You can filter with sets
of individual labels or with label categories. You can specify
inclusive filters, exclusive filters, or a combination of inclusive
and exclusive filters. For more information on filtering see
Detecting Labels in an Image.
When getting labels, you can specify MinConfidence
to control the
confidence threshold for the labels returned. The default is 55%. You
can also add the MaxLabels
parameter to limit the number of labels
returned. The default and upper limit is 1000 labels. These arguments
are only valid when supplying GENERAL_LABELS as a feature type.
Response Elements
For each object, scene, and concept the API returns one or more labels. The API returns the following types of information about labels:
Name - The name of the detected label.
Confidence - The level of confidence in the label assigned to a detected object.
Parents - The ancestor labels for a detected label. DetectLabels returns a hierarchical taxonomy of detected labels. For example, a detected car might be assigned the label car. The label car has two parent labels: Vehicle (its parent) and Transportation (its grandparent). The response includes the all ancestors for a label, where every ancestor is a unique label. In the previous example, Car, Vehicle, and Transportation are returned as unique labels in the response.
Aliases - Possible Aliases for the label.
Categories - The label categories that the detected label belongs to.
BoundingBox — Bounding boxes are described for all instances of detected common object labels, returned in an array of Instance objects. An Instance object contains a BoundingBox object, describing the location of the label on the input image. It also includes the confidence for the accuracy of the detected bounding box.
The API returns the following information regarding the image, as part of the ImageProperties structure:
Quality - Information about the Sharpness, Brightness, and Contrast of the input image, scored between 0 to 100. Image quality is returned for the entire image, as well as the background and the foreground.
Dominant Color - An array of the dominant colors in the image.
Foreground - Information about the sharpness, brightness, and dominant colors of the input image’s foreground.
Background - Information about the sharpness, brightness, and dominant colors of the input image’s background.
The list of returned labels will include at least one label for every detected object, along with information about that label. In the following example, suppose the input image has a lighthouse, the sea, and a rock. The response includes all three labels, one for each object, as well as the confidence in the label:
\{Name: lighthouse, Confidence: 98.4629\}
\{Name: rock,Confidence: 79.2097\}
\{Name: sea,Confidence: 75.061\}
The list of labels can include multiple labels for the same object. For example, if the input image shows a flower (for example, a tulip), the operation might return the following three labels.
\{Name: flower,Confidence: 99.0562\}
\{Name: plant,Confidence: 99.0562\}
\{Name: tulip,Confidence: 99.0562\}
In this example, the detection algorithm more precisely identifies the flower as a tulip.
This is a stateless API operation that doesn't return any data.
This operation requires permissions to perform the
rekognition:DetectLabels
action.

#detect_moderation_labels(params = {}) ⇒ Types::DetectModerationLabelsResponse
Detects unsafe content in a specified JPEG or PNG format image. Use
DetectModerationLabels
to moderate images depending on your
requirements. For example, you might want to filter images that
contain nudity, but not images containing suggestive content.
To filter images, use the labels returned by DetectModerationLabels
to determine which types of content are appropriate.
For information about moderation labels, see Detecting Unsafe Content in the Amazon Rekognition Developer Guide.
You pass the input image either as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.
You can specify an adapter to use when retrieving label predictions by
providing a ProjectVersionArn
to the ProjectVersion
argument.

#detect_protective_equipment(params = {}) ⇒ Types::DetectProtectiveEquipmentResponse
Detects Personal Protective Equipment (PPE) worn by people detected in an image. Amazon Rekognition can detect the following types of PPE.
Face cover
Hand cover
Head cover
You pass the input image as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. The image must be either a PNG or JPG formatted file.
DetectProtectiveEquipment
detects PPE worn by up to 15 persons
detected in an image.
For each person detected in the image the API returns an array of body parts (face, head, left-hand, right-hand). For each body part, an array of detected items of PPE is returned, including an indicator of whether or not the PPE covers the body part. The API returns the confidence it has in each detection (person, PPE, body part and body part coverage). It also returns a bounding box (BoundingBox) for each detected person and each detected item of PPE.
You can optionally request a summary of detected PPE items with the
SummarizationAttributes
input parameter. The summary provides the
following information.
The persons detected as wearing all of the types of PPE that you specify.
The persons detected as not wearing all of the types PPE that you specify.
The persons detected where PPE adornment could not be determined.
This is a stateless API operation. That is, the operation does not persist any data.
This operation requires permissions to perform the
rekognition:DetectProtectiveEquipment
action.

#detect_text(params = {}) ⇒ Types::DetectTextResponse
Detects text in the input image and converts it into machine-readable text.
Pass the input image as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, you must pass it as a reference to an image in an Amazon S3 bucket. For the AWS CLI, passing image bytes is not supported. The image must be either a .png or .jpeg formatted file.
The DetectText
operation returns text in an array of TextDetection
elements, TextDetections
. Each TextDetection
element provides
information about a single word or line of text that was detected in
the image.
A word is one or more script characters that are not separated by
spaces. DetectText
can detect up to 100 words in an image.
A line is a string of equally spaced words. A line isn't necessarily
a complete sentence. For example, a driver's license number is
detected as a line. A line ends when there is no aligned text after
it. Also, a line ends when there is a large gap between words,
relative to the length of the words. This means, depending on the gap
between words, Amazon Rekognition may detect multiple lines in text
aligned in the same direction. Periods don't represent the end of a
line. If a sentence spans multiple lines, the DetectText
operation
returns multiple lines.
To determine whether a TextDetection
element is a line of text or a
word, use the TextDetection
object Type
field.
To be detected, text must be within +/- 90 degrees orientation of the horizontal axis.
For more information, see Detecting text in the Amazon Rekognition Developer Guide.

#disassociate_faces(params = {}) ⇒ Types::DisassociateFacesResponse
Removes the association between a Face
supplied in an array of
FaceIds
and the User. If the User is not present already, then a
ResourceNotFound
exception is thrown. If successful, an array of
faces that are disassociated from the User is returned. If a given
face is already disassociated from the given UserID, it will be
ignored and not be returned in the response. If a given face is
already associated with a different User or not found in the
collection it will be returned as part of
UnsuccessfulDisassociations
. You can remove 1 - 100 face IDs from a
user at one time.

#distribute_dataset_entries(params = {}) ⇒ Struct
Distributes the entries (images) in a training dataset across the
training dataset and the test dataset for a project.
DistributeDatasetEntries
moves 20% of the training dataset images to
the test dataset. An entry is a JSON Line that describes an image.
You supply the Amazon Resource Names (ARN) of a project's training dataset and test dataset. The training dataset must contain the images that you want to split. The test dataset must be empty. The datasets must belong to the same project. To create training and test datasets for a project, call CreateDataset.
Distributing a dataset takes a while to complete. To check the status
call DescribeDataset
. The operation is complete when the Status
field for the training dataset and the test dataset is
UPDATE_COMPLETE
. If the dataset split fails, the value of Status
is UPDATE_FAILED
.

#get_celebrity_recognition(params = {}) ⇒ Types::GetCelebrityRecognitionResponse
Gets the celebrity recognition results for a Amazon Rekognition Video analysis started by StartCelebrityRecognition.
Celebrity recognition in a video is an asynchronous operation.
Analysis is started by a call to StartCelebrityRecognition which
returns a job identifier (JobId
).
When the celebrity recognition operation finishes, Amazon Rekognition
Video publishes a completion status to the Amazon Simple Notification
Service topic registered in the initial call to
StartCelebrityRecognition
. To get the results of the celebrity
recognition analysis, first check that the status value published to
the Amazon SNS topic is SUCCEEDED
. If so, call
GetCelebrityDetection
and pass the job identifier (JobId
) from the
initial call to StartCelebrityDetection
.
For more information, see Working With Stored Videos in the Amazon Rekognition Developer Guide.
GetCelebrityRecognition
returns detected celebrities and the time(s)
they are detected in an array (Celebrities
) of CelebrityRecognition
objects. Each CelebrityRecognition
contains information about the
celebrity in a CelebrityDetail object and the time, Timestamp
, the
celebrity was detected. This CelebrityDetail object stores information
about the detected celebrity's face attributes, a face bounding box,
known gender, the celebrity's name, and a confidence estimate.
GetCelebrityRecognition
only returns the default facial attributes
(BoundingBox
, Confidence
, Landmarks
, Pose
, and Quality
). The
BoundingBox
field only applies to the detected face instance. The
other facial attributes listed in the Face
object of the following
response syntax are not returned. For more information, see FaceDetail
in the Amazon Rekognition Developer Guide.
By default, the Celebrities
array is sorted by time (milliseconds
from the start of the video). You can also sort the array by celebrity
by specifying the value ID
in the SortBy
input parameter.
The CelebrityDetail
object includes the celebrity identifer and
additional information urls. If you don't store the additional
information urls, you can get them later by calling GetCelebrityInfo
with the celebrity identifer.
No information is returned for faces not recognized as celebrities.
Use MaxResults parameter to limit the number of labels returned. If
there are more results than specified in MaxResults
, the value of
NextToken
in the operation response contains a pagination token for
getting the next set of results. To get the next page of results, call
GetCelebrityDetection
and populate the NextToken
request parameter
with the token value returned from the previous call to
GetCelebrityRecognition
.
The returned response is a pageable response and is Enumerable. For details on usage see PageableResponse.

Amazon Rekognition Video inappropriate or offensive content detection
in a stored video is an asynchronous operation. You start analysis by
calling StartContentModeration which returns a job identifier
(JobId
). When analysis finishes, Amazon Rekognition Video publishes
a completion status to the Amazon Simple Notification Service topic
registered in the initial call to StartContentModeration
. To get the
results of the content analysis, first check that the status value
published to the Amazon SNS topic is SUCCEEDED
. If so, call
GetContentModeration
and pass the job identifier (JobId
) from the
initial call to StartContentModeration
.
For more information, see Working with Stored Videos in the Amazon Rekognition Devlopers Guide.
GetContentModeration
returns detected inappropriate, unwanted, or
offensive content moderation labels, and the time they are detected,
in an array, ModerationLabels
, of ContentModerationDetection
objects.
By default, the moderated labels are returned sorted by time, in
milliseconds from the start of the video. You can also sort them by
moderated label by specifying NAME
for the SortBy
input parameter.
Since video analysis can return a large number of results, use the
MaxResults
parameter to limit the number of labels returned in a
single call to GetContentModeration
. If there are more results than
specified in MaxResults
, the value of NextToken
in the operation
response contains a pagination token for getting the next set of
results. To get the next page of results, call GetContentModeration
and populate the NextToken
request parameter with the value of

.
For more information, see Searching Faces in a Collection in the Amazon Rekognition Developer Guide.
The search results are retured in an array, Persons
, of PersonMatch
objects. EachPersonMatch
element contains details about the matching
faces in the input collection, person information (facial attributes,
bounding boxes, and person identifer) for the matched person, and the
time the person was matched in the video.
GetFaceSearch
only returns the default facial attributes
(BoundingBox
, Confidence
, Landmarks
, Pose
, and Quality
). The
other facial attributes listed in the Face
object of the following
response syntax are not returned. For more information, see FaceDetail

#get_label_detection(params = {}) ⇒ Types::GetLabelDetectionResponse
Gets the label detection results of a Amazon Rekognition Video analysis started by StartLabelDetection.
The label detection operation is started by a call to
StartLabelDetection which returns a job identifier (JobId
). When the
label detection operation finishes, Amazon Rekognition publishes a
completion status to the Amazon Simple Notification Service topic
registered in the initial call to StartlabelDetection
.
To get the results of the label detection operation, first check that
the status value published to the Amazon SNS topic is SUCCEEDED
. If
so, call GetLabelDetection and pass the job identifier (JobId
) from
the initial call to StartLabelDetection
.
GetLabelDetection
returns an array of detected labels (Labels
)
sorted by the time the labels were detected. You can also sort by the
label name by specifying NAME
for the SortBy
input parameter. If
there is no NAME
specified, the default sort is by timestamp.
You can select how results are aggregated by using the AggregateBy
input parameter. The default aggregation method is TIMESTAMPS
. You
can also aggregate by SEGMENTS
, which aggregates all instances of
labels detected in a given segment.
The returned Labels array may include the following attributes:
Name - The name of the detected label.
Confidence - The level of confidence in the label assigned to a detected object.
Parents - The ancestor labels for a detected label. GetLabelDetection returns a hierarchical taxonomy of detected labels. For example, a detected car might be assigned the label car. The label car has two parent labels: Vehicle (its parent) and Transportation (its grandparent). The response includes the all ancestors for a label, where every ancestor is a unique label. In the previous example, Car, Vehicle, and Transportation are returned as unique labels in the response.
Aliases - Possible Aliases for the label.
Categories - The label categories that the detected label belongs to.
BoundingBox — Bounding boxes are described for all instances of detected common object labels, returned in an array of Instance objects. An Instance object contains a BoundingBox object, describing the location of the label on the input image. It also includes the confidence for the accuracy of the detected bounding box.
Timestamp - Time, in milliseconds from the start of the video, that the label was detected. For aggregation by
SEGMENTS
, theStartTimestampMillis
,EndTimestampMillis
, andDurationMillis
structures are what define a segment. Although the “Timestamp” structure is still returned with each label, its value is set to be the same asStartTimestampMillis
.
Timestamp and Bounding box information are returned for detected
Instances, only if aggregation is done by TIMESTAMPS
. If aggregating
by SEGMENTS
, information about detected instances isn’t returned.
The version of the label model used for the detection is also returned.
Note DominantColors
isn't returned for Instances
, although it
is shown as part of the response in the sample seen below.
Use MaxResults
parameter to limit the number of labels returned. If
there are more results than specified in MaxResults
, the value of
NextToken
in the operation response contains a pagination token for
getting the next set of results. To get the next page of results, call
GetlabelDetection
and populate the NextToken
request parameter
with the token value returned from the previous call to
GetLabelDetection
.
If you are retrieving results while using the Amazon Simple Notification Service, note that you will receive an "ERROR" notification if the job encounters an issue.
The returned response is a pageable response and is Enumerable. For details on usage see PageableResponse.

#index_faces(params = {}) ⇒ Types::IndexFacesResponse
Detects faces in the input image and adds them to the specified collection.
Amazon Rekognition doesn't save the actual faces that are detected. Instead, the underlying detection algorithm first detects the faces in the input image. For each face, the algorithm extracts facial features into a feature vector, and stores it in the backend database. Amazon Rekognition uses feature vectors when it performs face match and search operations using the SearchFaces and SearchFacesByImage operations.
For more information, see Adding faces to a collection in the Amazon Rekognition Developer Guide.
To get the number of faces in a collection, call DescribeCollection.
If you're using version 1.0 of the face detection model, IndexFaces
indexes the 15 largest faces in the input image. Later versions of the
face detection model index the 100 largest faces in the input image.
If you're using version 4 or later of the face model, image
orientation information is not returned in the OrientationCorrection
field.
To determine which version of the model you're using, call
DescribeCollection and supply the collection ID. You can also get the
model version from the value of FaceModelVersion
in the response
from IndexFaces
For more information, see Model Versioning in the Amazon Rekognition Developer Guide.
If you provide the optional ExternalImageId
for the input image you
provided, Amazon Rekognition associates this ID with all faces that it
detects. When you call the ListFaces operation, the response returns
the external ID. You can use this external image ID to create a
client-side index to associate the faces with each image. You can then
use the index to find all faces in an image.
You can specify the maximum number of faces to index with the
MaxFaces
input parameter. This is useful when you want to index the
largest faces in an image and don't want to index smaller faces, such
as those belonging to people standing in the background.
The QualityFilter
input parameter allows you to filter out detected
faces that don’t meet a required quality bar. The quality bar is based
on a variety of common use cases. By default, IndexFaces
chooses the
quality bar that's used to filter faces. You can also explicitly
choose the quality bar. Use QualityFilter
, to set the quality bar by
specifying LOW
, MEDIUM
, or HIGH
. If you do not want to filter
detected faces, specify NONE
.
Information about faces detected in an image, but not indexed, is
returned in an array of UnindexedFace objects, UnindexedFaces
. Faces
aren't indexed for reasons such as:
The number of faces detected exceeds the value of the
MaxFaces
request parameter.The face is too small compared to the image dimensions.
The face is too blurry.
The image is too dark.
The face has an extreme pose.
The face doesn’t have enough detail to be suitable for face search.
In response, the IndexFaces
operation returns an array of metadata
for all detected faces, FaceRecords
. This includes:
The bounding box,
BoundingBox
, of the detected face.A confidence value,
Confidence
, which indicates the confidence that the bounding box contains a face.A face ID,
FaceId
, assigned by the service for each face that's detected and stored.An image ID,
ImageId
, assigned by the service for the input image.
If you request ALL
or specific facial attributes (e.g.,
FACE_OCCLUDED
) by using the detectionAttributes parameter, Amazon
Rekognition returns detailed facial attributes, such as facial
landmarks (for example, location of eye and mouth), facial occlusion,
and other facial attributes.
If you provide the same image, specify the same collection, and use
the same external ID in the IndexFaces
operation, Amazon Rekognition
doesn't save duplicate face metadata.
The input image is passed either as base64-encoded image bytes, or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes isn't supported. The image must be formatted as a PNG or JPEG file.
This operation requires permissions to perform the
rekognition:IndexFaces
action.

returns the 64 largest faces in the image. It
lists the recognized celebrities in the CelebrityFaces
array and any
unrecognized faces in the UnrecognizedFaces
array.
RecognizeCelebrities
doesn't return celebrities whose faces aren't
among the largest 64 faces in the image.
For each celebrity recognized, RecognizeCelebrities
returns a
Celebrity
object. The Celebrity
object contains the celebrity
name, ID, URL links to additional information, match confidence, and a
ComparedFace
object that you can use to locate the celebrity's face
on the image.
Amazon Rekognition doesn't retain information about which images a
celebrity has been recognized in. Your application must store this
information and use the Celebrity
ID property as a unique identifier
for the celebrity. If you don't store the celebrity name or
additional information URLs returned by RecognizeCelebrities
, you
will need the ID to identify the celebrity in a call to the
GetCelebrityInfo operation.

#update_dataset_entries(params = {}) ⇒ Struct
Adds or updates one or more entries (images) in a dataset. An entry is a JSON Line which contains the information for a single image, including the image location, assigned labels, and object location bounding boxes. For more information, see Image-Level labels in manifest files and Object localization in manifest files in the Amazon Rekognition Custom Labels Developer Guide.
If the source-ref
field in the JSON line references an existing
image, the existing image in the dataset is updated. If source-ref
field doesn't reference an existing image, the image is added as a
new image to the dataset.
You specify the changes that you want to make in the Changes
input
parameter. There isn't a limit to the number JSON Lines that you can
change, but the size of Changes
must be less than 5MB.
UpdateDatasetEntries
returns immediatly, but the dataset update
might take a while to complete. Use DescribeDataset to check the
current status. The dataset updated successfully if the value of
Status
is UPDATE_COMPLETE
.
To check if any non-terminal errors occured, call ListDatasetEntries
and check for the presence of errors
lists in the JSON Lines.
Dataset update fails if a terminal error occurs (Status
=
UPDATE_FAILED
). Currently, you can't access the terminal error
information from the Amazon Rekognition Custom Labels SDK.
This operation requires permissions to perform the
rekognition:UpdateDatasetEntries
action.

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean
Polls an API operation until a resource enters a desired state.
Basic Usage
A waiter will call an API operation until:
- It is successful
- It enters a terminal state
- It makes the maximum number of attempts
In between attempts, the waiter will sleep.
# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)
Configuration
You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.
# poll for ~25 seconds
client.wait_until(waiter_name, params, {
max_attempts: 5,
delay: 5,
})
Callbacks
You can be notified before each polling attempt and before each
delay. If you throw :success
or :failure
from these callbacks,
it will terminate the waiter.
started_at = Time.now
client.wait_until(waiter_name, params, {
# disable max attempts
max_attempts: nil,
# poll for 1 hour, instead of a number of attempts
before_wait: -> (attempts, response) do
throw :failure if Time.now - started_at > 3600
end
})
Handling Errors
When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.
begin
client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
# resource did not enter the desired state in time
end
Valid Waiters
The following table lists the valid waiter names, the operations they call,
and the default :delay
and :max_attempts
values.
waiter_name | params | :delay | :max_attempts |
---|---|---|---|
project_version_running | #describe_project_versions | 30 | 40 |
project_version_training_completed | #describe_project_versions | 120 | 360 |
