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.
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,
