在 MATLAB Online 中打开

In which direction? Assuming left and right, you can use conv2() or imfilter():

img = imread('moon.tif');
diffImage = imfilter(img, [1, -1]);
imshow(diffImage, [])

localBinaryPattern.m

That would have been helpful to know in advance. I have no time to program this up for you but it's very similar to my local binary pattern demo where I get the values in a circle around the pixel like that. You just have to add or subtract them rather than take them as a binary number. See attached demo.
