How do I code a sediment identifier or classifier by beach sand grain size using images?

I need to develop a script that allows me, from images of beach sediment, to identify and classify grains by grain sizes.

I don't know how to do it or where to find it done.

Thank you

I heard of a study that looked at beach sand in Alaska and was able to classify where (what river) each grain of sand came from. It used morphometrics and Fourier Shape Descriptions. Sorry, I have no MATLAB code that that.
