TOOD: Task-aligned One-stage Object Detection

4 code implementations ICCV 2021 Chengjian Feng, Yujie Zhong, Yu Gao, Matthew R. Scott, Weilin Huang

One-stage object detection is commonly implemented by optimizing two sub-tasks: object classification and localization, using heads with two parallel branches, which might lead to a certain level of spatial misalignment in predictions between the two tasks.
