WebTo ensure good coverage of the foreground objects, we first generate a large set ofstatic object proposals in each frame. Since there can be many frames in the video, we need … The output of a region proposal network (RPN) is a bunch of boxes/proposals that will be passed to a classifier and regressor to eventually check the occurrence of objects. In nutshell , RPN predicts the possibility of an anchor being background or foreground, and refine the anchor. See more If you’re reading this post then I assume that you must have heard about RCNN family for object detection & if so then you must have come … See more The way CNN learns classification from feature maps, RPN also learns to generate these candidate boxes from feature maps. A typical Region proposal network can be demonstrated using below figure- Let’s understand above … See more In this step , a sliding window is run through the feature maps obtained from the last step . The size of sliding window is n*n (here 3×3 ). For each sliding window, a particular set of anchors are generated but with 3 different … See more So in the very first step , our input image goes through the Convolutional Neural Network and its last layer gives the features maps as output .
