Alpha matting is the process of decomposing an image into foreground and background regions, usually with the interest to extract the foreground object. This submission does just that. Begin by creating a trimap, comprising the known background and foreground regions, as well as the unlabeled boundary of the two regions. And let the algorithm handle the rest.

The alpha matting algorithm is due to the published work of:
Zheng & Kambhamettu, "Learning based digital matting", IEEE International Conference on Computer Vision (ICCV 2009).
