public class ChamferMask3DW3Float
extends ChamferMask3D
Implementation of Chamfer Weights for 3D images that manages three types of offsets, corresponding to orthogonal, square-diagonal and cube-diagonal neighbors. This implementation manages two series of weights, one for integer computation, the other one for floating-point computation.
