Method and apparatus for detecting disparity by using hierarchical stereo matching

摘要

The variation extracting method and an apparatus using a hierarchical stereo matching is provided. Based on a disparity image of the previous sub-layer performs the up-scale (up-scale) Matching of the upper layer to obtain a disparity image of the upper layer and performs an up-sampling (up-sampling) based on a disparity image of the upper layer to obtain an enhanced picture resolution variations. Obtaining a weight calculated by the term range (Range term) by using the derived image of the same layer, by applying the calculated weight to the disparity image of the layer to obtain a weight variation image.;
