#include <itkTimeVaryingVelocityFieldImageRegistrationMethodv4.h>
Interface method for the current registration framework using the time varying velocity field transform.
Output: The output is the updated transform which has been added to the composite transform.
This derived class from the ImageRegistrationMethodv4 class is specialized to handle time-varying velocity field transforms of which there are currently 2:
The latter is derived from the former and performs an optional spatial and temporal smoothing on the update and total velocity fields. Integration of the velocity field is performed using 4th order Runge Kutta and is performed using the class itkTimeVaryingVelocityFieldIntegrationImageFilter.
Optimization occurs in an iterative fashion where for each sample time point, t, in the velocity field, we integrate the velocity field in the range [0, t] to yield the displacement field which warps fixed image to time point t. Simultaneously, we integrate the velocity field in the range [t, 1] to yield the displacement field transform which warps the moving image to time point t. The metric derivative for each time point of the velocity field calculated in this way produces the normalized update field (or gradient) of the velocity field to be added to the total field at each iteration after being multiplied by the learning rate and optionally smoothed. Mathematically, this can be described as
where
gaussian smoothing on the total field gaussian smoothing on the update field learning rate the normalized velocity field where we normalize the velocity field at each time point separately by the max norm of the field at that time point. This is done due to a weakly necessary (but not sufficient) condition being that the velocity field have a constant norm for all time points.
