Reply to comment by Peantoo in [R] You Only Segment Once: Towards Real-Time Panoptic Segmentation [CVPR 2023] by Technical-Vast1314

OK, panoptic segmentation means doing two kinds of segmentation task together: semantic segmentation and instance segmentation. The semantic segmentation can only segment things like "sky", "car", "person", but it's hard to segment each instance. And instance segmentation is like object detection, which means it will predict a box with a mask on an instance~

Isn't semantic segmentation made redundant by the instance segmentation? Or is there a difference in coverage for the two tasks, in terms of the ground truth labels?
