Faster rcnn anchor free
Webpaper, we propose a novel anchor-free region pro-posal network (AF-RPN) to replace the original an-chor-based RPN in the Faster R-CNN framework to address the above problem. Compared with a vanilla RPN and FPN-RPN, AF-RPN can get rid of compli-cated anchor design and achieve higher recall rate on large-scale COCO-Text dataset.
