[Numpy-discussion] Simple pattern recognition

[Gökhan Sever]

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.
