After you create a face collection and store face vectors and/or user vectors, you can search a face collection for face matches. With Amazon Rekognition, you can search for faces in a collection that match:
-
A supplied face ID (SearchFaces). For more information, see Searching for a face with a face ID.
-
The largest face in a supplied image (SearchFacesByImage). For more information, see Searching for a face with an image.
-
Faces in a stored video. For more information, see Searching stored videos for faces.
-
Faces in a streaming video. For more information, see Working with streaming video events.
You can use the CompareFaces operation to compare a face in a source

The various Search operations seen in the following list compare a face (identified
either by a FaceId or an input image) with all faces stored in a given face
collection:
