Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::VoronoiSegmentationRGBImageFilter< TInputImage, TOutputImage >

Segmentation of 2D RGB images using Voronoi Diagram. This is not a standard 3 channel image filter, it also investigates the HSV color space information. from RGBHSV, the user can specify or by giving a prior binary mask, the algorithm will decide which 3 channels out of the 6 channels will be used for homogeneity testing. the homogeneity testing requires all the three testing channels to have the similar mean and standard deviation value from the gold-standard in the sense that the difference will be under the tolerance value.

Input parameters are: (1) Image data, in the format: itkImage<itkVector<PixelType,3>, 2>. (2) Object statistics: mean and standard deviation (3) Tolerance level for the classifier. This level is usually set around the mean and standard deviation values.

These parameters can also be automatically set by providing a binary image prior.

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, Vol.24, pp 173-180, 2000.
