Image segmentation algorithm I wonder if there are algorithms used to segment images efficiently. The ones I tested by now can not segment hair correctly as on this image:



I just want to know if someone can give me some efficient algorithms to segment the hair on this image for example without cutting it and so on (correct segmentation)

Note that I tested famous algorithms such as watershed, grabcut, mean shift ... but no one of them segments this hair correctly.

Thank you very much in advance.
You can find what you need here where a comparaison of lot of matting algorithms is done. You can see the rank of those algorithms' performances as well as online demonstration on a natural and complicated image.

From that study, you can guess that A Global Sampling Method for Alpha Matting is the best algorithm to resolve your problem. The algorithm is conceived by A Global Sampling Method for Alpha Matting

Hope this helps.
