The usual way of doing such things is to use PIL (Python Image Library) to load the image from file, then export it from PIL to a Python string in order to import from this string to an array of the targeted numerical module. Really curious if there is a direct way in any of the numerical packages, as it would save the time and effort of unnecessary conversions from PIL, ImageMagick or from other image libraries.
