基于SAD（square absolutely differences）的新的图像相关算法，并且最后使用WTA(winner take all）作为评估算法-Based on SAD (square absolutely differences) of the new image correlation algorithm, and the final use of WTA (winner take all) for evaluating the algorithm

图像匹配问题，利用彩色图像梯度与像素的SAD法得到图像左右视差图，并利用WTA法得到准确视差-Image matching, color image gradient pixel SAD obtained disparity map image around, and WTA method to get an accurate parallax
