Retina U-Net: Embarrassingly Simple Exploitation of Segmentation Supervision for Medical Object Detection

Jan 2019

tl;dr: The addition of full segmentation supervision at the last decoding layer to FPN boosts the performance of object detection.

Overall impression

This paper proposed an interesting idea to combine U-Net with FPN. This idea could be further extended by introducing deep supervision on every level of FPN, instead of just the last decoding layer at P0.
