Panoptic Feature Pyramid Networks

Jan 2019

tl;dr: Add a semantic segmentation branch to Mask RCNN with FPN yields SOTA results in panoptic segmentation.

Overall impression

The idea is related to Retina-Unet, but the ablation test here is more solid. A single network can perform both semantic and instance segmentation. But if we are only interested in instance segmentation, the benefit from the addition of semantic segmentation is mininal.

Key ideas
