I have image with some object at not solid background. I want to extract this objects like in gimp using “fuzzy select”. This can be an example:

Question is what is the best way to do it using python/PIL…
I suppose you would need some flood-fill algorithm (such as breadth-first-traversal) in which you stop exploring pixels with different color than black.
Wikipedia has an excellent explanation with animations and pseudo-code
