The result of erosion and dilation is called opening. On the one hand, this maintains to some extent the
original size of the regions while not losing the smoothing effect of erosion on the image. This name
stands for the operation of reducing convex bulges in the contour of the region. Thin connections
between regions are eliminated, broken borders between regions are connected, and small regions
disappear.
The opposite operation (first dilation, then erosion) is called closing. Concave bulges in the contours of
regions are filled in; connections are formed between adjacent regions.
The following example illustrates the operations "Open" and "Close" in two dimensions:
Open = E Dilation

Close = Di Erosion

The "cube cross" shape was used for the operations shown.
