Local Spatiotemporal Representation Learning for Longitudinally-consistent Neuroimage Analysis

1 code implementation9 Jun 2022 Mengwei Ren, Neel Dey, Martin A. Styner, Kelly Botteron, Guido Gerig

Recent self-supervised advances in medical computer vision exploit global and local anatomical self-similarity for pretraining prior to downstream tasks such as segmentation.

One-Shot Segmentation Representation Learning

Q-space Conditioned Translation Networks for Directional Synthesis of Diffusion Weighted Images from Multi-modal Structural MRI

1 code implementation24 Jun 2021 Mengwei Ren, Heejong Kim, Neel Dey, Guido Gerig

Further, such approaches can restrict downstream usage of variably sampled DWIs for usages including the estimation of microstructural indices or tractography.

Equivariant Spherical Deconvolution: Learning Sparse Orientation Distribution Functions from Spherical Data

1 code implementation17 Feb 2021 Axel Elaldi, Neel Dey, Heejong Kim, Guido Gerig

We then show improved downstream performance on fiber tractography measures on the Tractometer benchmark dataset.

Group Equivariant Generative Adversarial Networks

no code implementations ICLR 2021 Neel Dey, Antong Chen, Soheil Ghafurian

Recent improvements in generative adversarial visual synthesis incorporate real and fake image transformation in a self-supervised setting, leading to increased stability and perceptual fidelity.
