patch-denoise 1.3.1

Denoising method for sequence of images or volumes. Primarly targeting fMRI data.

This repository implements patch-denoising methods, with a particular focus on local-low rank methods.

The target application is functional MRI thermal noise removal, but this methods can be applied to a wide range of image modalities.

It includes several local-low-rank based denoising methods (see the documentation for more details):

1. MP-PCA

2. Hybrid-PCA

3. NORDIC

4. Optimal Thresholding

5. Raw Singular Value Thresholding

A mathematical description of theses methods is available in the documentation.

Installation
