Steps to perform semantic segmentation:

1. Click on Label type and select Semantic painting from the top left menu of the editor.

2. Select a category/class from the dropdown.

3. Paint Selection: Click on Paint with Brush using Left-click on the left-hand sidebar. Use Right-Click on the mouse for selecting Painting Mode (Brush or Polygon) to start painting.
