Image-processing basics
===

I have to do some image processing but I don't know where to start. My problem is as follows :-

I have a 2D fiber image, in which the fiber edges are denoted by white color and the inside of the fiber is black. I want to choose any black pixel inside the fiber, and travel from it along the length of the fiber. This will involve comparing the contrast with the surrounding pixels and then travelling in the desired direction.  My main aim is to find the length of the fiber

So can someone please tell me atleast where to start? I have made a rough algorithm in my mind on how to approach my problem but I don't know even which software/library to use.

Regards
Adi
