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.
