I have a color image that I want to convert to monochromatic. Also the image contains many broken/slightly deformed circles because it is a cross section of an object. I need to be able to recognize the centroids and radii of them. I have attached the picture below.

Note: If it isn't possible to convert to monochrome that isn't a huge deal
Here's a short blog post about an image processing task much like yours:

How to Count Cells, Annihilate Sailboats, and Warp the Mona Lisa

There are many ways of doing this and it's likely neccessary to tweak the code for your specific case. The Components functionality in the image processing tools are very useful for what you looking to do.
