Elastic Registration of 3D Deformable Objects
2012 International Conference on Digital Image Computing Techniques and Applications (DICTA), 2012A novel correspondence-less approach is proposed to find a non-linear aligning transformation between a pair of deformable 3D objects. Herein, we consider a polynomial deformation model, but our framework can be easily adapted to other common deformations. The basic idea of the proposed method is to set up a system of nonlinear equations whose solution

Deformable image registration based on elastodynamics
Machine Vision and Applications, 2015This paper presents a novel method for 2D inter-subject non-rigid image registration. It is motivated by the ideas derived from elastodynamics which is the subclass of linear elastic theory. We propose to model the non-rigid deformations as elastic waves which are characterized by elastodynamics wave equation. Our registration method is formulated in a

An algebraic framework for deformable image registration
2016 23rd International Conference on Pattern Recognition (ICPR), 2016This paper presents a novel approach to deformable image registration using a parametric transformation model. The aligning transformation is simply found by solving a system of non-linear equations. Each equation is generated by integrating the product of a set of polynomial functions and the image intensity function over corresponding image domains ...

Data-driven registration for local deformations
Pattern Recognition Letters, 1996We present a new data-driven feature-point registration method for image sequences. This method is based on a modified Kohonen network model that performs local non-affine transformations based on a point's neighbourhood context. This new method is ideal for non-real time applications where the situation is too complex to enable an operational ...

Registration and Modeling of Elastic Deformations of Fingerprints
2004We apply the methods of the theory of elasticity for two important problems in fingerprint based authentication: (1) registration of deformations up to the level of pixel-wise correspondence of two images; (2) parametric modeling and exact measurement of the natural deformations. The approach is based on the numerical solution of Navier linear PDE, the

Sliding Geometries in Deformable Image Registration
2012Regularization is used in deformable image registration to encourage plausible displacement fields, and significantly impacts the derived correspondences. Sliding motion, such as that between the lungs and chest wall and between the abdominal organs, complicates registration because many regularizations are global smoothness constraints that produce ...

Registration of local deformations in images
2008 Second International Conference on Electrical Engineering, 2008This paper proposes a radial basis function(RBF) with finite support to register non rigid local deformations present in a image pair. The criteria to evaluate accuracy of local transformation function is also proposed. Results of proposed RBF are analyzed and compared with the existing RBFs, based on the evaluation criteria and similarity measures ...

Hybrid Multimodal Deformable Registration with a Data-Driven Deformation Prior
2013Deformable registration for images with different contrast-enhancement and hence different structure appearance is extremely challenging due to the ill-posed nature of the problem. Utilizing prior anatomical knowledge is thus necessary to eliminate implausible deformations.
