Detailed Description

template<class TInputImage, class TProbabilityPrecisionType = float>
class itk::BayesianClassifierInitializationImageFilter< TInputImage, TProbabilityPrecisionType >

This filter is intended to be used as a helper class to initialize the BayesianClassifierImageFilter.

: The goal of this filter is to generate a membership image that indicates the membership of each pixel to each class. These membership images are fed as input to the Bayesian classfier filter.

Parameters: Number of classes: This defines the number of classes, which will determine the number of membership images that will be generated. The user must specify this.

: Membership functions: The user can optionally plugin in any membership function. The number of membership functions plugged in should be the same as the number of classes. If the user does not supply membership functions, the filter will generate membership functions for you. These functions are Gaussian density functions centered around 'n' pixel intensity values, . These 'n' values are obtained by running K-means on the image. In other words, the default behaviour of the filter is to generate Gaussian mixture model for the input image.

Inputs and Outputs: The filter takes a scalar Image as input and generates a VectorImage, each component of which represents memberships of each pixel to the class .

Template parameters: This filter is templated over the input image type and the data type used to represent the probabilities (defaults to float).
