A brief overview of R-CNN, Fast R-CNN and Faster R-CNN

WebOct 11, 2024 · Faster RCNN is the modified version of Fast RCNN. The major difference between them is that Fast RCNN uses selective search for generating Regions of Interest, while Faster RCNN uses “Region Proposal Network”, aka RPN. RPN takes image feature maps as an input and generates a set of object proposals, each with an objectness score … WebJun 17, 2024 · RCNN系列目標檢測,大致分為兩個階段:一是獲取候選區域(region proposal 或 RoI),二是對候選區域進行分類判斷以及邊框回歸。 Faster R-CNN其實也是符合兩個階段,只是Faster R-CNN使用RPN網絡提取候選框,後面的分類和邊框回歸和R-CNN差不多。所以有時候我們可以將Faster R-CNN看成RPN部分和R-CNN部分。
