Learn how to manage labeling classes in your annotation jobs, including adding new classes, editing existing ones, and protecting classes from accidental changes.

​
Step 1: Add a New Class

Use the bottom of the labeler right panel to add new class entries. When adding a class, you can specify:
  • Class Name: The name of the annotation class
  • Super Class (optional): Used to group classes of the same family together for certain model training purposes

​
Step 2: Edit or Remove a Class

Once a class is created, you have options to manage it. For each class, you can:
  • Edit: Click the edit button to enter edit mode
  • Remove: Click the trash button to remove this class
Note: Removing a class will also remove all associated annotations with this class.

​
Step 3: Modify Class Properties

When in edit mode, you can modify various properties of the class. You can modify:
  • Class Name: Change the name of the class
  • Super Class Name: Update or add a super class grouping
  • Class Color: Adjust the color used to display this class in annotations
After making changes:
  • Click the ✓ (tick emoji) to save your changes
  • Click the ✕ (cross emoji) to cancel changes

​
Step 4: View Associated Annotations

Each class displays the number of annotations associated with it. This helps you track which classes are being used and how extensively they’ve been annotated.

​
Step 5: Lock Classes to Prevent Changes

Users of the workspace can click the lock button to lock/unlock class edits to protect against mistaken changes. When classes are locked:
  • Other users cannot make edits to existing classes
  • Other users cannot remove existing classes in this job
  • This protects your class structure from accidental modifications
Happy labeling!
