public class SoChessboardDistanceMapProcessing
extends SoImageVizEngine

SoChessboardDistanceMapProcessing engine. The SoChessboardDistanceMapProcessing engine computes the chessboard distance transformation.

This engine is based upon a recursive method and work in two iterations. It is used for particle segmentation, before a Watershed engine.

This engine calculates the distance function of a binary image onto a gray level image, as the sum of successive erosions. The output image is a 16-bits signed image.

In the output image , a voxel belonging to a particle , takes an intensity equal to the distance in voxel units to the boundary. For a rectangular grid the distance is defined as:

Where denotes the so called Chessboard distance:
