Member Function Documentation
| virtual double irtkImageFluidRegistration::Evaluate | ( | ) | [protected, virtual] |
Evaluates the registration.
This function evaluates the registration by looping over the target image and interpolating the transformed source image while filling the joint histogram. This function returns the value of the similarity measure using Similarity().
Implements irtkImageRegistration.
Reimplemented in irtkImageFluidRegistration2D.
| virtual double irtkImageFluidRegistration::EvaluateDerivative | ( | int | , | |
| double | ||||
| ) | [protected, virtual] |
Evaluates the registration.
This function evaluates the registration by looping over the target image and interpolating the transformed source image while filling the joint histogram. This function returns the value of the similarity measure using Similarity(). This function uses the cached result of any previous call to Evaluate() and recalculates the similarity measure in the specified region of interest.
Reimplemented in irtkImageFluidRegistration2D.
| virtual double irtkImageFluidRegistration::EvaluateGradient | ( | float | , | |
| float * | ||||
| ) | [protected, virtual] |
Evaluates the gradient of the similarity metric.
This function evaluates the gradient of the similarity metric of the registration by looping over the target image and interpolating the transformed source image while filling the joint histogram. The partial derivatives are approximated using a finite difference scheme. The step size for the finite difference scheme is passed as a parameter to the function. The function returns the norm of the gradient vector as well as the gradient vector containing the partial derivatives.
Reimplemented from irtkImageRegistration.
