| Abstract: | Image stereo matching is one of the most important issues in stereo vision.Reliability of depth maps and computational cost of algorithm is the key point for implementing real time robust applications.In the paper,a region based stereo matching algorithm is developed for extracting depth information from a color stereo image pair,which is based on region growing.The algorithm includes two parts,i.e.root selection process and region growing process,and needs less calculation time to obtain disparity map.Filt... |
