WebJan 31, 2024 · At the core of it, if you look at the source code, RPN is just a convolution layer with the number of maps=number of anchors per location, in you case it's 9. As any convolution layer, it's connected to the previous layer (also convolution, with 256 maps) using a kernel, in your case 3x3.
