Erosion and dilation. The erosion of a binary image f by a structuring element s (denoted f s) produces a new binary image g = f s with ones in all locations (x,y) of a structuring element's origin at which that structuring element s fits the input image f, i.e. g(x,y) = 1 is s fits f and 0 otherwise, repeating for all pixel coordinates (x,y). Erosion and dilation constitute two of the fundamental operations of binary and grayscale digital image processing. These operations are useful in applications such as noise removal, feature delineation, object measurement and counting, and estimating the size distribution of features in a digital image without actual measurement.

Erosion in Morphological Image Processing: For sets A and B in Z 2 (Binary Image), erosion of A by B is denoted by AвЉ–B. It is the set of all points z such that B, shifted or translated by z, is contained in A. It is used for removing irrelevant size details from a binary image. Erosion shrinks the image. It leads to thinning. It can strip during image processing (such as during opening and closing). III. CONCLUSION We show some digital images to illustrate the effect of dilation-erosion operators in images. It is known that binary mathematical morphology dilation expands the image and erosion shrinks it. Erosion yields a smaller image than the original and dilation in opposite.
