#include <itkVersorTransformOptimizer.h>
Implement a gradient descent optimizer.
VersorTransformOptimizer is a variant of the gradient descent optimizer implmented in RegularStepGradientDescentOptimizer.
Versors are not in a vector space, for that reason, the classical gradient descent algorithm has to be modified in order to be applicable to Versors (unit quaternions) that form the group SO(3).
The Versor space has only three degrees of freedom, even though Versors are represented using four values.
This optimizer assumes that the CostFunction to be optimized has an itk::Versor as parameter.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
