Detailed Description

template<class TInputImage, class TOutputImage, class TBinaryPriorImage = Image< unsigned char, 2 >>
class itk::VoronoiSegmentationImageFilterBase< TInputImage, TOutputImage, TBinaryPriorImage >

Base class for VoronoiSegmentationImageFilter.

Voronoi SegmentationImageFilter is a class of segmenation algorithms that works on 2D image. Begin with certain number of seeds, VoronoiSegmentationImageFilter first partition the image plane to voronoi regions, and testing each region by some homogeneity operators, which need to be implemented in the private method: virtual bool TestHomogeneity(IndexList &Plist); after testing, all the regions are classified as either "internal" or "external" region and the "boundary" regions was defined as an "external" region that has at least one "internal" region as its neighbor. the algorithm then added seed points to the "boundary" regions (on the edges) and recursively "split" the boundary region until all the "boundary" become sufficiently small. the output of the segmentation can be either a binary object, which is the collection of all the "internal" region. Or a binary boundary delineate, which is defined as the connected lines between seed points of "boundary" region. This class is a base class for voronoi segmenation, single channel or multiple channel image segmenation can be implemented by deriving imagefilters from this class, by implementing the virtual methods

Detailed information about this algorithm can be found in: " Semi-automated color segmentation of anatomical tissue," C. Imelinska, M. Downes, and W. Yuan Computerized Medical Imaging and Graphics, Vor.24, pp 173-180, 2000.
