Detailed Description

template<class TInputVectorImage, class TLabel = unsigned char>
class itk::FuzzyClassifierImageFilter< TInputVectorImage, TLabel >

Performs defuzzification on a membership image.

The filter implements the defuzzification (i.e., the assignment of each pixel to a particular class based on their memberships) by applying a Maximum Decision Rule to the membership image.

If a pixel of the membership image has values -1, that pixel is assumed to be a background pixel and should be ignored. The value of the label assigned to those pixels will be equal to the number of classes. Otherwise, the pixel values of the resulting label map will indicate the classes they correspond to (e.g. labels with value 0 belong to the class 0, labels with value 1 belong to the first class, etc.). Thus the range of label values is 0 to the number of classes.

Inputs and Outputs

The input to this filter is an itk::VectorImage that represents pixel memberships to 'n' classes. You may use a subclass of FuzzyClassifierInitializationImageFilter to generate the membership images or specify your own.

The output of the filter is a label map (an image of unsigned char is the default).

Template parameters

This filter is templated over the input vector image type and the data type of the output label map (defaults to unsigned char).

Input image typedef support (types inherited from the superclass).

Input vector image type representing the membership of a pixel to a particular class. This image has arrays as pixels, the number of elements in the array is the same as the number of classes to be used.

Output image typedef support (types inherited from the superclass).

The value of each element in the label map is the label of the winner class for the corresponding pixel of the input image. A negative value in the matrix indicates that the corresponding pixel of the input image is ignored (i.e. it's a background value).
