since I asked these questions in this mailing list, I decided to start
with 2.7, beside it, I installed 3.3 from source to port my learning
to latest version.
http://www.python.org/doc/
Yes, the best start point is this link!

may be the best library/tools for industrial level image processing is
OpenCV, Nothing an compare to it.

as you said, these are really low level. If I have to stick to python
maybe I use theme.

you are righ, it seems PIL is good for prepare input data befor processing.

I goggled, Beside python ruby have some good features, I don't know what to do,
Now I want to learn python, it's really great for develop.
