I think what you are talking about falls more under the field of
"computer vision" or "image understanding". I quick google search will
yield quite a bit of information. There are also many textbooks
written on the subject.

As far as libraries go, I have not seen much in the way of computer
vision for Python. The two libraries that I do know about are both
written in C++:

   Intel's Open Source Computer Vision Library
   http://www.intel.com/research/mrl/research/opencv/

   LTI-Lib
   http://ltilib.sourceforge.net/

I think this all depends on how much prior knowledge you have about
the structure of the image, and the shapes of the things you are
looking for.
