| 摘 要： | 为了解决传统Rank非参数变换匹配算法存在的问题,提出了一种基于改进Rank变换的图像匹配算法.引入Rank变换并研究其局限性,将变换窗口内所有像素的灰度平均值作为匹配像素的灰度值.对于和匹配像素相对位置相差为1个单位的邻域像素,其灰度值保持不变；对于其他位置像素灰度值用二维双线性插值法获得.将图像实现改进Rank变换...

| Abstract: | To solve the problem of traditional Rank non-parametric matching algorithm,an image matching algorithm based on improved Rank transform is presented.Rank transform is introduced and its limitation is discussed.The mean gray value of all the pixels in the matching window is taken as the gray value of the matching pixel.The gray values of the neighborhood pixels whose relative positions are one unit equal to the matching pixel are kept the same.The gray values of the neighborhood pixels at the other positions... |
