Detailed Description

template<typename TImage, typename TImageMask, typename 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).

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.
