A friend at Greenpeace asked me if there's a way to automate counting micro-plastic particles from beach surveys.
I played around a bit with the Image Sequencer, but it wonder if there's a relatively simple filter I can apply to the RGB channels to find edges, without having to predefine the colors I want to extract.
I attached an example image, which could also be on a dark background if that would help with the lighter pieces. Once we have a good filtering process, we'd want to build a simple webapp to let people take photos and do counts themselves.
