Detailed Description

template<class TInputImage, class TMembershipFunction>
class itk::ImageModelEstimatorBase< TInputImage, TMembershipFunction >

Base class for model estimation from images used for classification.

itkImageModelEstimatorBase is the base class for the ImageModelEstimator objects. It provides the basic function definitions that are inherent to ImageModelEstimator objects.

This is the SuperClass for the ImageModelEstimator framework. This is an abstract class defining an interface for all such objects available through the ImageModelEstimator framework in the ITK toolkit.

The basic functionality of the ImageModelEstimator framework base class is to generate the models used in classification applications. It requires input images and a training image to be provided by the user. This object supports data handling of multiband images. The object accepts the input image in vector format only, where each pixel is a vector and each element of the vector corresponds to an entry from 1 particular band of a multiband dataset. A single band image is treated as a vector image with a single element for every vector. The classified image is treated as a single band scalar image.

EstimateModels() is a pure virtual function making this an abstract class. The template parameter is the type of membership function the ImageModelEstimator populates.

A membership function represents a specific knowledge about a class. In other words, it should tell us how "likely" is that a measurement vector (pattern) belong to the class.

As the method name indicates, you can have more than one membership function. One for each classes. The order of the membership calculator becomes the class label for the class that is represented by the membership calculator.
