Finding vertices of a non-rectangle

[Greg McKaskle]

I think you have about exhausted the capabilities of the particle library.

The next step, if you are ready for it is to use the bounding box from the particles to efficiently inspect areas of the original image with edge detection, line fitting, or even rectangle fitting. I believe there are ones that work on binary, but the better ones work on monochrome images. Doing them on the full frame will be quite expensive, but on a small subset should be fine.
