Pillow is great for simple image processing. Converting between formats,
resizing, cropping, rotating. simple filters - that kind of thing. The
kind of thing you might otherwise do with GIMP, you might say.
For more in-depth image analysis, scipy.ndimage and scikit-image are
your friends. Obviously they work better with the numpy/scipy ecosystem.
And, as MRAB points out, there's also OpenCV, which is fantastic for
certain types of problems (have a look at the docs). For some fields
(e.g. astronomy) there are also more specialized packages that may help.
In short, if you images are pictures, have a look at Pillow. If your
images are data, have a look at scikit-image, scipy.ndimage, and maybe
more specialized packages like OpenCV or astropy.
