Web4 Jan 2024 · Erosion: It is useful for removing small white noises. Used to detach two connected objects etc. Dilation: In cases like noise removal, erosion is followed by dilation. Because, erosion removes white noises, but it also shrinks our object. So we dilate it. Since noise is gone, they won’t come back, but our object area increases.
