WebJun 4, 2015 · An RPN is a fully convolutional network that simultaneously predicts object bounds and objectness scores at each position. The RPN is trained end-to-end to generate high-quality region proposals, which are used by Fast R-CNN for detection. We further merge RPN and Fast R-CNN into a single network by sharing their convolutional features---using ... WebJul 13, 2024 · In Fast R-CNN, the region proposals are created using Selective Search, a pretty slow process is found to be the bottleneck of the overall object detection process. So, we need a better technique where it gives less than 2000 region proposals, faster than selective search, as accurate as selective search or better, and should be able to propose ...
