Point-Set Anchors for Object Detection, Instance Segmentation and Pose Estimation

6 Jul 2020Fangyun WeiXiao SunHongyang LiJingdong WangStephen Lin

A recent approach for object detection and human pose estimation is to regress bounding boxes or human keypoints from a central point on the object or person. While this center-point regression is simple and efficient, we argue that the image features extracted at a central point contain limited information for predicting distant keypoints or bounding box boundaries, due to object deformation and scale/orientation variation...
