Detailed Description

template<class VM>
class cmtk::VoxelMatchingElasticFunctional_Template< VM >

Functional that evaluates a voxel-based similarity measure.

This class defines the type of functional that is optimized during voxel-based registration. It holds references to reference and floating data and computes similarity as well as its gradient w.r.t. a given transformation.

The metric to be optimized is given by a template parameter, therefore allowing inlined code to be generated for efficient evaluation.
