Computer simulation results show that, by using of the new method, better discrimination and a sharper correlation peak can be achieved. 计算机模拟结果表明，采用新的方法可以锐化相关峰并得到更好的识别效果。
During the corner feature match operation, the initial matching points are determined by region gray level correlation calculation with removing mean value normalization method. 在角点特征匹配过程中，利用去均值归一化相关法进行区域灰度相关运算，从而确定出初始匹配点对。
