macJNet: weakly-supervised multimodal image deformable registration using joint learning framework and multi-sampling cascaded MIND

BioMedical Engineering OnLine, 2023
Deformable multimodal image registration plays a key role in medical image analysis. It remains a challenge to find accurate dense correspondences between multimodal images due to the significant intensity distortion and the large deformation. macJNet is

Attention Guided Policy Optimization for 3D Medical Image Registration

IEEE Access, 2023
Learning-based image registration approaches typically learn to map from input images to a transformation matrix. Regarding the current deep-learning-based image rigid registration approaches learn a transformation matrix in a one-shot way.

Homologous point transformer for multi-modality prostate image registration [PDF]

PeerJ Computer Science, 2022
Registration is the process of transforming images so they are aligned in the same coordinate space. In the medical field, image registration is often used to align multi-modal or multi-parametric images of the same organ.

Dimensionality reduction of medical image descriptors for multimodal image registration

Current Directions in Biomedical Engineering, 2015
Defining similarity forms a challenging and relevant research topic in multimodal image registration. The frequently used mutual information disregards contextual information, which is shared across modalities.

Multimodal Medical Image registration using Discrete Wavelet Transform

JISR on Computing, 2013
In image processing, image registration develops a relationship between two images using optimal transformation where the images could have been taken at various times, sources or devices, or from different perspectives.

Finite element surface registration incorporating curvature, volume preservation, and statistical model information [PDF]

, 2013
We present a novel method for nonrigid registration of 3D surfaces and images. The method can be used to register surfaces by means of their distance images, or to register medical images directly.
