英文摘要：

An improved graph cut stereo matching algorithm is presented,using RGB color space model and color similarity.In the matching algorithm,the color squared intensity difference is the original matching cost establishing the energy function.After constructing a network,the minimization of energy function is obtained by network-flow theory,and then the disparity data are obtained in order to achieve directly matching of color images.Experimental results show that the algorithm can obtain more precise disparity map,which demonstrates the practical value of the algorithm.
