|Determining optical flow between two volumes||Previous Top Next|
In order to determine the optical flow between two rigidly registered datasets, we make use of the demonsRegistration non-rigid registration module. Do this after the rpgid landmark-based pre-registration and after having extracted a common sub-volume from all datasets.
This is an ITK module, so you have to use the ITK-enabled version of DeVIDE. For each pair of successive volumes, determine the optical flow by making use of a network like the one shown in the figure below:
