Hello all,
I want to be able to count predefined simple rectangle shapes on an image as shown like in this one: http://img7.imageshack.us/img7/2327/particles.png
Which is in my case to count all the blue pixels (they are ice-snow flake shadows in reality) in one of the column.
What is the way to automate this task, which library or technique should I study to tackle it.
Thanks.

You should check out the ndimage subpackage in scipy.
This tutorial should help you get started:
http://docs.scipy.org/doc/scipy/reference/tutorial/ndimage.html
The section on “segmentation and labeling” will be particularly useful for you.
Best,

Right into the eye.
“Segmentation is the process of separating objects of interest from
the background.”
Once I finish this task, I should be able to count the occurrences of the shadowed instances so that I would have an idea regarding to their sizes.
