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:

enter image description here

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.

Hi, Segmentation of hair is very very tough task.

I think the only algorithms which can handle things like that are those which solve optimization problem (Something like Colorization by Optimization).

I'm not sure they will be fast enough for the average user.

Otherwise you need to take one of the methods you mentioned and optimize it to its best performance point, which is what usually done by commercial companies.
