Image processing libraries in python

[tejaswi]

Hello everyone,
I was looking to work with images in python. I saw two packages
related to this, Pillow and scipy.ndimage.  I was wondering what
purposes each of these serve.
I've previously used matlab/octave's image processing facilities and
found them quite easy to work with, so is scipy the way to go in that
case.
Thank you,
