WebIt proceeds in two stages: Initially we extract a set of possible depth values for each pixel using NCC as a matching metric. We then solve a multi-label discrete MRF model which yields the depth assignment for every pixel. One of the key features in this process is the inclusion of an unknown state in the MRF model.
