Hi, 1) I am in the process of testing a trained and validated CNN with images from ILSVRC2012. 2) My question is the following: What is the img_mean.npy file and what is reason for subtracting the img_mean (shape = 3L, 256L, 256L) when loading the images? 3) Interestingly, I obtain quite different results related to the top-5 probabilities, whether I subtract the mean or not in the loading process, e.g., when I use a .hkl file (shape = 3L, 256L, 256L, 256L) containing 256 images. 4) For each new (single) image that I load and test, do I need to generate and subtract a img_mean? Any comments that you may offer would be helpful. Best, Arnold
