Detection of Edges Using Mathematical Morphological Operators

Edges form the outline of an object. An edge is the boundary between an object and the background, and indicates the boundary between overlapping objects also. So, by identifying edges in an image accurately, all the objects can be located and basic properties such as area, perimeter and shape can be measured. Therefore, edge detection is used to find the discontinuities in surface orientation, changes in material properties and variations in scene illuminations. In this paper, implementation of various morphological operators is done for medical images.
