count and Evaluating area

How can I do a estimating of the approximate particle size distribution (granulometry) of the stones bellow?

[Alvim Rios Jr]

I made a first attempt manually cutting each stone one by one as shown above (yes, it was hard work. I would not want to repeat it).

However I do not know how to produce the results I need in matlab.
