我正在尝试计算窗口中每个像素周围的对比度NxN，并将结果保存在新图像中，其中新图像中的每个像素是旧图像中其周围区域的对比度。从另一篇文章我得到了这个：
1) Convert the image to say LAB and get the L channel
2) Compute the max for an NxN neighborhood around each pixel
3) Compute the min for an NxN neighborhood around each pixel
4) Compute the contrast from the equation above at each pixel.
5) Insert the contrast as a pixel value in new image.
目前我有以下内容：
1) Convert the image to say LAB and get the L channel
2) Compute the max for an NxN neighborhood …
