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.

Compute functional value with volume clipping.
This function iterates over all voxels of the reference image that - after applying the current coordinate transformation - are located inside the mode image. This set of voxels is determined on-the-fly by an extension of Liang and Barsky's "Parameterized Line-Clipping" technique.
From the resulting sequence of reference/floating voxel pairs, the selected voxel-based similarity measure (metric) is computed.

Compute functional gradient as a thread.
This function (i.e., each thread) iterates over all parameters of the current warp transformation. Among all active (i.e., not disabled) parameters, it selects the ones that have an index with modulus equal to the threads index when divided by the total number of threads. For these parameters, the thread computes the partial derivative of the functional by finite-difference approximation.

| size_t cmtk::ImagePairAffineRegistrationFunctionalTemplate< VM >::m_NumberOfThreads |
Number of threads that this object was created for.
This is the actual maximum number of threads running at any time, but not necessarily the number of parallel tasks to be completed. All duplicated data structures are generated with the multiplicity given by this value. It is determined from Threads when the object is first instanced. It cannot be changed afterwards.
