Inheritance diagram for itk::fem::ImageMetricLoad< TMoving, TFixed >:
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).

Sets the pointer to solution vector. This function is automatically called by the Solver class on every load object. Some types of external Loads may need access to previous values of solution vector. If a derived class needs that, it should implement this function, and store the passed pointer accordingly. If the result vector is not required, the functionn should be left unimplemented, so that only the dummy implementation in base class is called.
