Connectivity: In image processing, the object we are interested in is usually a combination of
interconnected pixels. Therefore, in order to obtain an area, we must calculate all the connected
areas that are contained in the area after division. On a rectangular pixel grid, there are two
definitions of connectivity. The first one is that the two pixels have a common edge, that is, one
pixel is above, below, to the left or to the right of the other pixel, which is called 4-connectivity.
The second definition is the extension of the first definition. The adjacent pixels on the diagonal
line are also included, which is called 8-connectivity.
