Catalano.Imaging.Concurrent.Filters.Erosion

All Implemented Interfaces:

IApplyInPlace

public class Erosion
extends java.lang.Object
implements IApplyInPlace

Erosion operator from Mathematical Morphology. The filter assigns minimum value of surrounding pixels to each pixel of the result image. Surrounding pixels, which should be processed, are specified by structuring element: 1 - to process the neighbor, 0 - to skip it. The filter especially useful for binary image processing, where it removes pixels, which are not surrounded by specified amount of neighbors. It gives ability to remove noisy pixels (stand-alone pixels) or shrink objects. The filter accepts 8, 24 bpp images for processing.
