Fast free-form deformation using graphics processing units [PDF]

open access: yesComputer 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

A free‐form surface flattening algorithm that minimizes geometric deformation energy

open access: yesIET 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

open access: yesIEEE 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 ...

Multi-Shape Free-Form Deformation Framework for Efficient Data Transmission in AR-Based Medical Training Simulators

open access: yesApplied Sciences, 2021
Augmented reality medical training simulators can provide a realistic and immersive experience by overlapping the virtual scene on to the real world. Latency in augmented reality (AR) medical training simulators is an important issue as it can lead to ...

Shape Optimization of Blended-Wing-Body Underwater Gliders Based on Free-Form Deformation

open access: yesXibei 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 ...

Free form deformation and symmetry constraint‐based multi‐modal brain image registration using generative adversarial nets

open access: yesCAAI 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

open access: yesMedical 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]

open access: yes, 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 ...

Simulation analysis of deformation spring-back of free-form surface composite with cellular foam filling

open access: yesMaterials Research Express, 2021
Due to the complex thermo-chemical-mechanical coupling during the curing and forming process of composite materials, spring-back is commonly observed after forming, which makes the shape of parts after curing and forming deviate from the design shape ...
