I am doing image analysis on a few images of stained slides. I was hoping to find the percentage of the vessel that is red, green, yellow and orange. Any ideas on how to go about this? Thanks in advance for your help. As per a request, here's a link to the kind of picture I am dealing with. It is a picture of one of my stained slides.: http://tinypic.com/r/2mwi995/5 EDIT: for those that are interested, the differentiation of color allows us to determine the thickness of the collagen fibers. Each respective thickness has a different color. Any help would be appreciated

For a first step, I would take a look at the demos that Image Analyst has posted to File Exchange. That should get you familiar with the basic functions of interest.

Hi Siddharth,
I would take a look at the imread function build into Matlab. For an RGB image of size M-by-N, it will import the image as an M-by-N-by-3 Matrix, where red, green, and, and blue are separated into each Z dimension of the imported image.
