  A new improvement is proposed for stereo matching which gives a solution to disparity map in terms of edge energy. We decompose the stereo matching into three parts: sparse disparity estimation for image-pairs, edge energy model and final disparity refinement. A three-step procedure is proposed to solve them sequentially. At the first step, we perform an initial disparity model using the ordering constraint and interpolation to obtain a more efficient sparse disparity space. At the second step, we apply the energy function by the edge constraints that exist in both images. The last step is a kind of disparity filling. We determine disparity values in target regions based on global optimization. The proposed three-step simple stereo matching procedure yields excellent quantitative and qualitative results with Middlebury data sets in a fast way.
