Detailed Description

template<class TImage, class TImageMask, class TBiasField>
class itk::MRIBiasEnergyFunction< TImage, TImageMask, TBiasField >

a cost function for optimization

This is a wrapping class which provides interfaces between images, the bias field, the internal energy function (CompositeValleyFunction), and the Optimizer.

This class is templated over the type of the input image (TImage), the image mask (which tells which pixels in the input image should be included for energy value calculation), and the bias field (TBiasField).
