Excuse me for the clumsy explanation: my goal is to calculate the receptive field in the original layer for a given field in the output one.
The figure represents an image (3x224 x 224) going through 17 Conv2d and Maxpool layers (one layer between each frame of the figure,please ignore the last 2 frames) I plot in orange the slice of interest in the output tensor: what I am looking for is a way to recover the white slices for each intermediate frame,i.e the portion of the previous tensor which will generate the next on,everything based on the slice of interest of the last tensor (orange)
