Hi nouiz, If you can make it work, I for one would really appreciate if it was possible to pool an image where the output of the pooling operation has more than 512 columns. I need that since in my network I pool only vertically and not horizontally. I instead use dilated convolution layers where I dilate in the x-direction; this is in order not to loose any spatial information horizontally which is important in my case. For now I will have to crop the image to 512 columns but I would really prefer not to.
