Detailed Description
template<class TMoving, class TFixed>
class itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >
General image pair load that uses the itkFiniteDifferenceFunctions.
This load computes FEM gravity loads by using derivatives provided by itkFiniteDifferenceFunctions (e.g. mean squares intensity difference.) The function responsible for this is called Fg, as required by the FEMLoad standards. It takes a vnl_vector as input. We assume the vector input is of size 2*ImageDimension. The 0 to ImageDimension-1 elements contain the position, p, in the reference (moving) image. The next ImageDimension to 2*ImageDimension-1 elements contain the value of the vector field at that point, v(p). The metrics return both a scalar similarity value and vector-valued derivative. The derivative is what gives us the force to drive the FEM registration. These values are computed with respect to some region in the Fixed image. This region size may be set by the user by calling SetMetricRadius. As the metric derivative computation evolves, performance should improve and more functionality will be available (such as scale selection).

| ) | [static, inherited] |
Read object of any derived type from stream.
This static function creates an object of a class, which is derived from FEMLightObject. The class of object is first determined from the stream, then the object of that class is constructed using the FEMObjectFactory. Finally the data for this object is read from the stream, by calling the Read() member function.

Write an object to the output stream. Call this member to write the data members in the current object to the output stream.

The class name is obtained by calling the virtual ClassID() member function and passing the result to the FEMObjectFactory.
Implementations of Write member funtion in derived classes should first call the parent's implementation of Write and finaly write whatever they need.
