Rcnn head
WebJan 13, 2024 · Ross Girshick, the author of RCNN, came up with the idea of running the CNN just once per image and then finding a way to share that computation across the 2,000 regions. In Fast RCNN, we feed the input image to the CNN, which in turn generates the convolutional feature maps. Using these maps, the regions of proposals are extracted.
