CP2: Copy-Paste Contrastive Pretraining for Semantic Segmentation

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Huiyu Wang, Chen Wei, Alan Yuille, Wei Shen | Summary: Recent advances in self-supervised contrastive learning yield good image-level representation, which favors classification tasks but usually neglects pixel-level detailed information, leading to unsatisfactory transfer performance to dense prediction tasks such as semantic segmentation. In this […]
