Toward Minimal Misalignment at Minimal Cost in One-Stage and Anchor-Free Object Detection

1 code implementation16 Dec 2021 Shuaizheng Hao, Hongzhe Liu, Ningwei Wang, Cheng Xu

Common object detection models consist of classification and regression branches, due to different task drivers, these two branches have different sensibility to the features from the same scale level and the same spatial location.
