Step 1 - If you select Image Category as one of the annotation types, you will be asked to configure the project separate from object detection annotations.
1. Create a category (e.g. Time)
2. Create category properties (e.g. Afternoon, Evening)
3. Create a category group
📽️ You can select whether to set Video Categories per frame. If you toggle Per Frame, you can label objects in different properties by each frame.
Step 1 - This is the page you will see if you selected Box, Polyline, Polygon Segmentation and/or Keypoint as the annotation type.
1. Create the list of object classes by clicking
+ on the top of the Object Class card. You can start to designate all the relevant object classes for your current project.
2. Select the annotation type for each object class in the drop-down list.
You can set class properties to further define the object's characteristics.
1. Select the Object Class that you want to add a property then click
+ on the Class Property box
2. You can set the property types as Multiple Choice, Multiple Selection, and Free Response.
3. For Multiple Choice and Multiple Select types, you can set the property names and also set as a required property by clicking the Required toggle.
📽️ On a video project, you can set the object properties per frame. If you toggle Per Frame, you can label different object property values per frame.
You can map the object classes with the Auto-Label object classes as following.
1. Open the Configure Auto-Label window by clicking the blue star located directly to the right of each object class.
2. Select the object class that you want to set Auto-Label.
3. Select all the classes on the check box that you want to label using Auto-Label AI.
4. Auto-Label configuration is done once you click
Save on the top right corner.
❗ Availability of Auto-Label AI depends on the annotation type. You can find more details here
You can set the annotation color for each object class. Setting each class with different colors to distinguish each other can help improve labeling and validation efficiency, especially for complex projects with a lot of object classes.
1. Click the colored circle located on the left of the Object Class.
2. Select a color.
❗ You cannot change the colors of objects that are already labeled
You can set the minimum/maximum number of how many annotations of each object class can exist in a label. This option is useful to avoid human errors when you know how many annotations should exist in a label. Assignees will not be able to submit a label if this requirement is not met.
1. Click the object class you want to set the min/max annotations per image
2. Enter the number on the field located on the bottom right corner of the page
Minimum : The default value is None. The value cannot be negative or higher than the maximum.
Maximum : The default value is None. The value cannot be negative or lower than the minimum.
Next on the left bottom if you are done.
