Detailed Description

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

Perform the segmentation of 2D images (single channel) by Voronoi Diagram. Used as a node of the segmentation toolkits. The homogeneity operator here is the testing of mean and standar deviation value. By setting the tolerance level, the "internal" region was defined as those that is closed to the gold-standard value in the sense that the difference is within the tolerance value.

See VoronoiSegmentationImageFilterBase for detail description of voronoi segmenation principles.

The parameters here are:

the estimation of the statistics of the object. (mean and std.)
the tolerance for the classification. (around the mean ans std. estimated value).

The parameters can also be automatically set by given a prior, as a binary image.

Detail 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.
