Dilation is a method used in image processing to enlarge the white areas of the binary image. The structuring element is a 3x3 rectangle (using the 8 nearest pixels). Combiningerosion anddilation allows you to perform opening and closing operations, which remove individual black or white pixels, or smooth out the borders.
It is generally adviced to use the same number of dilation and erosion interactions.
