What is the convention for image dimensions in Torch? I'm not a torch user, but am reading some code and I need to know if Torch typically represents an RGB image as {height, width, channels} or as {channels, width, height} as I think I'm reading out of the code I'm looking at.
If you are using the image package (which is the usual way to go), then it usually represents images as tensors of size (channels, height, width).
