I can't really find any data on how to go about normalizing the input for the following VGG-16 model I am using https://gist.github.com/baraldilorenzo/07d7802847aaad0a35d3
Right now I am inputting a black and white image (copied 3 times to make it compatible). I have the colors normalized between 0 and 1. I am not sure if this is correct for VGG-16. Is the VGG model expecting mean - std normalization? Or does it not really matter?
