I am working with Python and PyQt4. I am looking a library with which I can find the outline path of an image (bitmap). With “outline path” I mean a polygon, which separates filled (non-transparent) pixels in the middle of the image from transparent pixels surrounding them.
I can not find anything via google, which kind of makes me wonder if I am using the correct search terms.
Thanks!
OpenCV has a function called FindContours which does what I want.
