1 connectivity In the image, the smallest unit is the pixel, and there are 8 critical pixels around each pixel. There are three common adjacency relationships: 4 adjacency, 8 adjacency and D adjacency. As shown in the figure below: 4 adjacency: the 4 neighborhood of pixel p (x, y) is: (x+1, y); (x-1，y)； (x，y+1)； (x, y-1), N4 § is u ...
