Morphology Erode

Mathematical morphology is a method of processing digital images on the basis of shape. Morphing is available during the working over images. Morphology Erode makes to the background, as dilation makes to the foreground. With this function one can remove islands which are smaller than the radius of a structuring element, for a given image and a structuring element.

Radius and shape of a structuring element for the erode and dilate operators are specified by the correspoding controls.
