THB-splines: The truncated basis for hierarchical splines
The construction of classical hierarchical B–splines can be suitably modified in order to define locally supported basis functions that form a partition of unity. We will show that this property can be obtained by reducing the support of basis functions defined on coarse grids, according to finer levels in the hierarchy of splines. This truncation not only decreases the overlapping of supports ...
متن کاملNon-rigid Registration Using Free-form Deformations
A deformable registration approach for medical images of same dimensionality is proposed. The popular free-form deformations (FFD) setting is utilized to characterize deformations based on a grid of control points. B-splines serve the purpose of interpolating the dense deformation field from a given control point configuration. The central idea is to combine the FFD method with well-understood ...
متن کاملRegistration Using Sparse Free-Form Deformations
Non-rigid image registration using free-form deformations (FFD) is a widely used technique in medical image registration. The balance between robustness and accuracy is controlled by the control point grid spacing and the amount of regularization. In this paper, we revisit the classic FFD registration approach and propose a sparse representation for FFDs using the principles of compressed sensi...

متن کاملTemporal sparse free-form deformations
FFD represent a widely used model for the non-rigid registration of medical images. The balance between robustness to noise and accuracy in modelling localised motion is typically controlled by the control point grid spacing and the amount of regularisation. More recently, TFFD have been proposed which extend the FFD approach in order to recover smooth motion from temporal image sequences. In t...
