public abstract class AbstractMorphologyFilter
extends Object
implements ImageFilter

Abstract class for mathematical morphology filters. The basic idea in binary morphology is to probe an image with a simple, pre-defined shape, drawing conclusions on how this shape fits or misses the shapes in the image. This simple "probe" is called structuring element, and is itself a binary image. Typical structuring elements are 3x3 square and 3x3 cross (i.e. a 3x3 "plus sign" image). http://en.wikipedia.org/wiki/Mathematical_morphology#Binary_morphology http://en.wikipedia.org/wiki/Structuring_element
