Detailed Description

Implement a gradient descent optimizer for the VersorRigid3DTransform parameter space.

VersorRigid3DTransformOptimizer 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 and an itk::Vector as parameters.

Member Function Documentation

virtual::itk::LightObject::Pointer itk::VersorRigid3DTransformOptimizer::CreateAnother ( void  ) const
virtual

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.

Reimplemented from itk::RegularStepGradientDescentBaseOptimizer.

virtual const char* itk::VersorRigid3DTransformOptimizer::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods).

static Pointer itk::VersorRigid3DTransformOptimizer::New ( )
static

Method for creation through the object factory.
