Detailed Description
template<class TMoving, class TFixed>
class itk::fem::ImageMetricLoad< TMoving, TFixed >
General image pair load that uses the itkImageToImageMetrics.
LoadImageMetric computes FEM gravity loads by using derivatives provided by itkImageToImageMetrics (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).
Then, we evaluate the derivative at the point p+v(p) with respect to some region of the target (fixed) image by calling the metric with the translation parameters as provided by the vector field at 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).

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.
