Your Task
When you work on a video frame object detection task, you need to select a category from the Label category menu on the right side of your worker portal to start annotating. After you've chosen a category, draw annotations around objects that this category applies to. To learn more about the tools you see in your worker UI, refer to the Tool Guide.
After you've added a label, you may see a downward pointing arrow next to the label in the Labels menu. Select this arrow and then select one option for each label attribute you see to provide more information about that label.
You may see frame attributes under the Labels menu. These attributes will appear on each frame in your task. Use these attribute prompts to enter additional information about each frame.
To edit an annotation, select the label of the annotation that you want to edit in the Labels menu or select the annotation in the frame. When you edit or delete an annotation, the action will only modify the annotation in a single frame.
If you are working on a task that includes a bounding box tool, use the predict next icon to predict the location of all bounding boxes that you have drawn in a frame in the next frame. If you select a single box and then select the predict next icon, only that box will be predicted in the next frame. If you have not added any boxes to the current frame, you will receive an error. You must add at least one box to the frame before using this feature.
Note
The predict next feature will not overwrite manually created annotations. It will only add annotations. If you use predict next and as a result have more than one bounding box around a single object, delete all but one box. Each object should only be identified with a single box.
After you've used the predict next icon, review the location of each box in the next frame and make adjustments to the box location and size if necessary.
The following graphic demonstrates how to use the predict next tool:
For all other tools, you can use the Copy to next and Copy to all tools to copy your annotations to the next or all frames respectively.
