class itk::ScalarImageKmeansImageFilter< TInputImage, TOutputImage >
Classifies the intensity values of a scalar image using the K-Means algorithm.
Given an input image with scalar values, it uses the K-Means statistical classifier in order to define labels for every pixel in the image. The filter is templated over the type of the input image. The output image is predefined as having the same dimension of the input image and pixel type unsigned char, under the assumption that the classifier will generate less than 256 classes.
You may want to look also at the RelabelImageFilter that may be used as a postprocessing stage, in particular if you are interested in ordering the labels by their relative size in number of pixels.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
Reimplemented from itk::Object.

Set/Get the UseNonContiguousLabels flag. When this is set to false the labels are numbered contiguously, like in {0,1,3..N}. When the flag is set to true, the labels are selected in order to span the dynamic range of the output image. This last option is useful when the output image is intended only for display. The default value is false.

Verifies that the process object has been configured correctly, that all required inputs are set, and needed parameters are set appropriately. If not valid an exceptions will be thrown.
This method is called before UpdateOutputInformation is propagated to the inputs.
The ProcessObject's implementation verifies that the NumberOfRequiredInputs are set and not null.
Reimplemented from itk::ProcessObject.
