CPSS-FAT: A consistent positive sample selection for object detection with full adaptive threshold.

•Discussing limitations of IoU-based and center-point assignment strategies and revealing their inconsistencies in the open world.•Weight IoU score with the normalized center-distance for better alignment of anchor-object named the consistent positive sample selection (CPSS) method.•To keep conformity with CPSS, introduce a consistent location quality estimation method.•According to the occlusion degree of an object, adopt the full adaptive threshold method to find out more objects.•Achieving the best performance overperforming most popularized detectors on MS COCO 2017.
