SPaM: soft patch matching for non-rigid pointcloud registration

open access: yesFrontiers in Robotics and AI, 2023
3d reconstruction of deformable objects in dynamic scenes forms the fundamental basis of many robotic applications. Existing mesh-based approaches compromise registration accuracy, and lose important details due to interpolation and smoothing ...

A Survey of Non-Rigid 3D Registration [PDF]

open access: yes, 2022
Non-rigid registration computes an alignment between a source surface with a target surface in a non-rigid manner. In the past decade, with the advances in 3D sensing technologies that can measure time-varying surfaces, non-rigid registration has been ...

Facial optical flow estimation via neural non-rigid registration

open access: yesComputational Visual Media, 2022
Optical flow estimation in human facial video, which provides 2D correspondences between adjacent frames, is a fundamental pre-processing step for many applications, like facial expression capture and recognition.

Toward Computing Cross-Modality Symmetric Non-Rigid Medical Image Registration

open access: yesIEEE Access, 2022
This paper describes a new non-rigid approach to register images from same- and cross-imaging modalities such as magnetic resonance imaging, computed tomography, and 3D rotational angiography.

Adaptive enhanced affine transformation for non‐rigid registration of visible and infrared images

open access: yesIET Image Processing, 2021
Non‐rigid registration, performing well in all‐weather and all‐day/night conditions, directly determine the reliability of visible (VIS) and infrared (IR) image fusion.

Learning intervention-induced deformations for non-rigid MR-CT registration and electrode localization in epilepsy patients

open access: yesNeuroImage: Clinical, 2016
This paper describes a framework for learning a statistical model of non-rigid deformations induced by interventional procedures. We make use of this learned model to perform constrained non-rigid registration of pre-procedural and post-procedural ...

Adaptive Non-Rigid Point Set Registration Based on Variational Bayesian [PDF]

open access: yesXibei Gongye Daxue Xuebao, 2018
For the existence of outliers in non-rigid point set registration, a method based on Bayesian student's t mixture model(SMM) is proposed. Under the framework of variational Bayesian, the point set registration problem is converted to maximize the ...

Effects of reusing baseline volumes of interest by applying (non-)rigid image registration on positron emission tomography response assessments. [PDF]

open access: yesPLoS ONE, 2014
OBJECTIVES: Reusing baseline volumes of interest (VOI) by applying non-rigid and to some extent (local) rigid image registration showed good test-retest variability similar to delineating VOI on both scans individually.

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

open access: yes, 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.
