#include <itkQuaternionRigidTransformGradientDescentOptimizer.h>
Implement a gradient descent optimizer.
QuaternionRigidTransformGradientDescentOptimizer is an extension to the simple gradient descent optimizer implmented in GradientDescentOptimizer. At each iteration the current position is updated according to
p(n+1) = p(n) + learningRate * d f(p(n)) / d p(n)
The learning rate is a fixed scalar defined via SetLearningRate(). The optimizer steps through a user defined number of iterations; no convergence checking is done. The first four components of p are assumed to be the four components of the quaternion. After each update, the quaternion is normalized to have a magnitude of one. This ensures the the transform is purely rigid.

Advance one step following the gradient direction.

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.
