Ok, I responded a bit quickly yesterday,

So here's the doc from find_boundaries (you can get that by running `find_boundaries?` in an ipython)

Definition:find_boundaries(**label_img) Docstring:Return bool array where boundaries between labeled regions are True.

So you see that find_boundaries work on a labeled image, so my guess is you first need to threshold your image, and only then find the boundaries.

It's not clear from what you say what exactly you want to segment out of the image, but maybe your work flow would include some colorspace conversion (for exemple RGB to HSV), then a thresholding, and then find_boundaries)...

Hope this helps, Guillaume
