Classes

A class defines the name of an object to be labeled, e.g., car or pedestrian. To create a class, go to Annotation Specification and click on Add Class.

Import Classes

You can use the import classes option to bulk import classes from a CSV file.

Custom options

1. Semantic Segmentation - Instance Aware

Identify each instance of an object within the image for a class by selecting the Instance Aware option. For example, in the above image, each car is annotated as an instance of the Car class and is also given an ID: Car#1 and Car#2

2. Landmark Annotation - Min and Max Points

A landmark annotation consists of one or more points labeled in an object. You can use the min and max points option to set a range for the number points for annotations belonging to a class.

3. Edge Labeling for Line annotation

The Edge Labeling feature allows the user to further segment a line with a given class into multiple segments where each of these segments can be given individual attributes. You can select Enable Segments option to enable edge-labeling for a class.
