A free‐form surface flattening algorithm that minimizes geometric deformation energy
IET Image Processing, 2022 Based on the analysis of the advantages and disadvantages of existing surface flattening algorithms, this paper proposes a free‐form surface flattening algorithm that minimizes geometric deformation by combining the advantages of the geometric flattening

Free-Form Deformation Parameterization on the Aerodynamic Optimization of Morphing Trailing Edge
Applied Mechanics, 2023 Every aerodynamic optimization is proceeded by a parameterization of the studied aerial object, and due to its influence on the final optimization process, careful attention should be made in choosing the appropriate parameterization method.

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 ...

Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor [PDF]
, 2007 We derive general relations between grain boundaries, rotational deformations, and stress-free states for the mesoscale continuum Nye dislocation density tensor. Dislocations generally are associated with long-range stress fields.

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 ...

On ${\cal N}{=}\,2$ supersymmetric Ruijsenaars-Schneider models [PDF]
, 2020 We construct an ${\cal N}{=}\,2$ supersymmetric extension of $n$-particle Ruijsenaars-Schneider models. The guiding feature is a deformation of the phase space.

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 ...
