Annotation with SAM 2 - Images and Videos
Annotation of images and videos depends on your Ontology. Our Ontology
E2E Fruit Ontology has the following label types:
- Bounding boxes
- Polygons
- Bitmasks
- Classifications
- Annotators labelling data
- Reviewers reviewing labels created by Annotators
- Team Manager managing the Annotators and Reviewers
- Project Admin managing the Project and exporting labels

Prepare to Label
Team Manager or Project Admin
Team Manager or Project Admin
The Team Manager or Project Admin can prioritize certain data to be labelled and reviewed first. Let’s prioritize the 
Set Priority to 
blueberries, cherries, and apples to be labelled first by setting the priority for those files to 75.Access ProjectSet Priority to 75Annotators
Annotators
Annotators can configure the Annotate Label Editor so they can more effectively and efficiently label data.

Annotators
Annotators use SAM 2 to annotate fruit in the Dataset using object labels. Classifications are manually annotated. We’ll focus on Bounding BoxesWe’ll use SAM 2 bounding boxes to label

blueberries, cherries, apples (object labels) and whether the fruit is ripe (classifications).You can approve labels/classifications on a task one at a time (from the left panel) or all at once (using the Approval all button).
When there is an issue with labels/classifications, Reviewers can:
- Reject the task and add a comment about why a task was rejected. Rejected tasks go back to the person who added the labels/classifications.
- Edit labels directly using the Edit labels button and then approve the task.
