3D facial attractiveness enhancement using free form deformation
Journal of King Saud University: Computer and Information Sciences, 2022 Physical attractiveness has an important and great influence in human social life as it was widely linked to the possession of a variety of positive qualities that makes an individual better than the others, as well as offering many advantages to the ...

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

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 ...

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.

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.

CAAI Transactions on Intelligence Technology, 2023 Multi‐modal brain image registration has been widely applied to functional localisation, neurosurgery and computational anatomy. The existing registration methods based on the dense deformation fields involve too many parameters, which is not conducive ...

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
