Non-Rigid Registration for Infrared and Visible Images via Gaussian Weighted Shape Context and Enhanced Affine Transformation

open access: yesIEEE Access, 2020
Image registration is a prerequisite for image fusion from multiple modalities, such as infrared (IR) and visible (VIS) images. Although there have been many various methods of image registration, non-rigid registration for IR and VIS images is still ...

A Robust and Accurate Two-Step Auto-Labeling Conditional Iterative Closest Points (TACICP) Algorithm for Three-Dimensional Multi-Modal Carotid Image Registration. [PDF]

open access: yesPLoS ONE, 2016
Atherosclerosis is among the leading causes of death and disability. Combining information from multi-modal vascular images is an effective and efficient way to diagnose and monitor atherosclerosis, in which image registration is a key technique. In this

Robust Rigid Shape Registration Method Using a Level Set Formulation

open access: yes, 2010
This paper presents a fast algorithm for robust registration of shapes implicitly represented by signed distance functions(SDF). The proposed algorithm aims to recover the transformation parameters( scaling, rotation, and translation) by minimizing the ...

Non-Parametric 3D Shape Warping [PDF]

open access: yes, 2010
A method is presented for non-rigid alignment of a source shape to a target shape through estimating and interpolating point-wise correspondences between their surfaces given as point clouds.

Robust non-rigid point set registration using student's-t mixture model. [PDF]

open access: yesPLoS ONE, 2014
The Student's-t mixture model, which is heavily tailed and more robust than the Gaussian mixture model, has recently received great attention on image processing.

Variational image registration using inhomogeneous regularization [PDF]

open access: yes, 2014
We present a generalization of the convolution basedvariational image registration approach, in which differentregularizers can be implemented by conveniently exchangingthe convolution kernel, even if it is nonseparableor nonstationary.

Deformable and articulated 3D reconstruction from monocular video sequences [PDF]

open access: yes, 2012
PhDThis thesis addresses the problem of deformable and articulated structure from motion from monocular uncalibrated video sequences. Structure from motion is defined as the problem of recovering information about the 3D structure of scenes imaged by a

Non-Rigid Point Set Registration via Adaptive Weighted Objective Function

open access: yesIEEE Access, 2018
Non-rigid point set registration is a fundamental problem in many fields related to computer vision, medical image processing, and pattern recognition. In this paper, we develop a new point set registration method by using an adaptive weighted objective ...

A Fully Unsupervised Deep Learning Framework for Non-Rigid Fundus Image Registration

open access: yesBioengineering, 2022
In ophthalmology, the registration problem consists of finding a geometric transformation that aligns a pair of images, supporting eye-care specialists who need to record and compare images of the same patient.

Non-rigid Free-Form 2D-3D Registration Using Statistical Deformation Model [PDF]

open access: yes, 2015
This paper presents a non-rigid free-from 2D-3D registration approach using statistical deformation model (SDM). In our approach the SDM is first constructed from a set of training data using a non-rigid registration algorithm based on b-spline free-form
