                <element name="DESCRIPTION" text="This algorithm performs morphological operations (erosion and dilation) on an image. &#10;&#10;Erosion to reduce shape size, whereas dilation increases it. That is, erosion removes cells of the boundaries of objects in a image, while dilation adds celss to the boundaries of objects.&#10;&#10;The following figure shows the effect of applying both an erosion (a) and a dilation operation (b).&#10;&#10;" description="Description" type="0">
