DeepAtlas: Joint Semi-Supervised Learning of Image Registration and Segmentation

uncbiag/DeepAtlas 17 Apr 2019

Specifically, in a one-shot-scenario (with only one manually labeled image) our approach increases Dice scores (%) over an unsupervised registration network by 2. 7 and 1. 8 on the knee and brain images respectively.

FlowReg: Fast Deformable Unsupervised Medical Image Registration using Optical Flow

iamlab-ryerson/flowreg 24 Jan 2021

The photometric loss minimizes pixel intensity differences differences, the smoothness loss encourages similar magnitudes between neighbouring vectors, and a correlation loss that is used to maintain the intensity similarity between fixed and moving image slices.

Leveraging Unsupervised Image Registration for Discovery of Landmark Shape Descriptor

riddhishb/self-supervised-landmarks 13 Nov 2021

We use landmark-driven image registration as the primary task to force the neural network to discover landmarks that register the images well.

Symmetric Transformer-based Network for Unsupervised Image Registration

MingR-Ma/SymTrans 28 Apr 2022

Medical image registration is a fundamental and critical task in medical image analysis.

Fourier-Net: Fast Image Registration with Band-limited Deformation

xi-jia/fourier-net 29 Nov 2022

Specifically, instead of our Fourier-Net learning to output a full-resolution displacement field in the spatial domain, we learn its low-dimensional representation in a band-limited Fourier domain.

RFR-WWANet: Weighted Window Attention-Based Recovery Feature Resolution Network for Unsupervised Image Registration

mingr-ma/rfr-wwanet 7 May 2023

Furthermore, shifted window partitioning operations are inflexible, indicating that they cannot perceive the semantic information over uncertain distances and automatically bridge the global connections between windows.

Fourier-Net+: Leveraging Band-Limited Representation for Efficient 3D Medical Image Registration

xi-jia/fourier-net 6 Jul 2023

Instead of directly predicting a full-resolution displacement field, our Fourier-Net learns a low-dimensional representation of the displacement field in the band-limited Fourier domain which our model-driven decoder converts to a full-resolution displacement field in the spatial domain.

Residual Aligner-based Network (RAN): Motion-separable structure for coarse-to-fine discontinuous deformable registration

jianqingzheng/res_aligner_net Medical Image Analysis 2023

Deformable image registration, the estimation of the spatial transformation between different images, is an important task in medical imaging.

High-Resolution Maps of Left Atrial Displacements and Strains Estimated with 3D CINE MRI and Unsupervised Neural Networks

cgalaz01/aladdin_cmr_la 14 Dec 2023

We create maps of LA Displacement Vector Field (DVF) magnitude and LA principal strain values from images of 10 healthy volunteers and 8 patients with cardiovascular disease (CVD).
