Dvd-hq - information about high-quality dvd and video compression. We present a novel algorithm for segmentation of natural images that harnesses the principle of minimum description length (mdl) our method is based on observations that a homogeneously textured region of a natural image can be well modeled by a gaussian distribution and the region boundary can be effectively coded by an adaptive chain code.
