Fast free-form deformation using graphics processing units [PDF]
Computer Methods and Programs in Biomedicine, 2010 A large number of algorithms have been developed to perform non-rigid registration and it is a tool commonly used in medical image analysis. The free-form deformation algorithm is a well-established technique, but is extremely time consuming. In this paper we present a parallel-friendly formulation of the algorithm suitable for graphics processing unit

An Effective Mesh Deformation Approach for Hull Shape Design by Optimization
Journal of Marine Science and Engineering, 2021 A method for the morphing of surface/volume meshes suitable to be used in hydrodynamic shape optimization is proposed. Built in the OpenFOAM environment, it relies on a Laplace equation that propagates the modifications of the surface boundaries ...

Image Deformation Estimation via Multiobjective Optimization
IEEE Access, 2022 The free-form deformation model can represent a wide range of non-rigid deformations by manipulating a control point lattice over the image. However, due to a large number of parameters, it is challenging to fit the free-form deformation model directly ...

Temporal sparse free-form deformations
Medical Image Analysis, 2013 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

Registration Using Sparse Free-Form Deformations [PDF]
, 2012 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 ...

Isotropic-Cholesteric Transition of a Weakly Chiral Elastomer Cylinder [PDF]
, 2008 When a chiral isotropic elastomer is brought to low temperature cholesteric phase, the nematic degree of freedom tends to order and form a helix. Due to the nemato-elastic coupling, this also leads to elastic deformation of the polymer network that is ...

Shape Optimization of Blended-Wing-Body Underwater Gliders Based on Free-Form Deformation
Xibei Gongye Daxue Xuebao, 2020 Currently developed underwater gliders can be roughly divided into the two types:traditional configuration and unconventional configuration. As a type of underwater gliders with unconventional configuration, a blended-wing-body (BWB) underwater glider ...
