Detailed Description

template<class TFixedImage, class TMovingImage, class TMaskImage, class TMesh, class TDeformationField>
class itk::fem::PhysicsBasedNonRigidRegistrationMethod< TFixedImage, TMovingImage, TMaskImage, TMesh, TDeformationField >

Perform a non-rigid registration of two 3D images using a set of feature points, block matching and linear elastic model.

PhysicsBasedNonRigidRegistrationMethod takes a fixed image, a moving image with an optional mask and a mesh as inputs and generates a dense deformation field image as an output.

This filter is intended to be used for driving the process of Physics- Based Non-Rigid Registration. It computes feature points from the moving image, then computes displacements of the feature points in the fixed image via block-matching, then computes deformation field of a whole image using linear elastic model[ M. Bierling, Displacement estimation by hierarchical block matching, Proc. SPIE Vis. Comm. and Image Proc., vol. 1001, pp. 942-951, 1988. ].

The filter is templated over fixed image, moving image, mask, mesh and deformation field image.
