HighRes-net is presented, the first deep learning approach to MFSR that learns its sub-tasks in an end-to-end fashion, and shows that by learning deep representations of multiple views, it can super-resolve low-resolution signals and enhance Earth Observation data at scale.
The primary results of synthetic and field data show promising interpolation performances of the adopted CNN-POCS method in terms of the signal-to-noise ratio, dealiasing, and weak-feature reconstruction, in comparison with the traditional [Formula] prediction filtering, curvelet transform, and block-matching 3D filtering methods.
The proposed PGD-Net is a learned proximal gradient descent framework that directly incorporates the forward acquisition and Bloch dynamic models within a recurrent learning mechanism, that adopts a compact neural proximal model for de-aliasing and quantitative inference.
An iterative deep learning plug-and-play reconstruction approach to MRF which is adaptive to the forward acquisition process and shows consistent dealiasing performance against both acquisition schemes and accurate mapping of tissues’ quantitative bio-properties.
The first adaptive diffusion prior for MRI reconstruction, AdaDiff, is proposed to improve performance and reliability against domain shifts, and achieves superior or on par within-domain performance.
A comprehensive analysis of hard pixel errors, categorizing them into three types: false responses, merging mistakes, and displacements is conducted, revealing a quantitative association between hard pixels and aliasing, which is distortion caused by the overlapping of frequency components in the Fourier domain during downsampling.
A new Spatiotemporal Fourier Neural Operator (SFNO) that learns maps between Bochner spaces, and a new learning framework to address issues in turbulent flow modeling by the Navier-Stokes Equations (NSE).
Adding a benchmark result helps the community track progress.
