# Locally-Rank-One-Based Joint Unmixing and Demosaicing for Snapshot Spectral Images

This repository contains a MATLAB implementation for the methods described in the following article:

**K. Abbas, M. Puigt, G. Delmaire, and G. Roussel (2024).**  
*"Locally-Rank-One-Based Joint Unmixing and Demosaicing Methods for Snapshot Spectral Images. Part I: A Matrix-Completion Framework."*  
*IEEE Transactions on Computational Imaging, 10, 848-862.*  
DOI: [10.1109/TCI.2024.3402322](https://doi.org/10.1109/TCI.2024.3402322)

## Overview
This project implements a matrix-completion framework for joint unmixing and demosaicing of snapshot spectral images, leveraging locally rank-one approximations and sparsity techniques as outlined in the referenced article. The code is provided under the MIT License (see below).

## Requirements
- MATLAB (version R20XXx or later recommended)
- To reproduce all the figures of the paper, you need to download the following functions: `PPID`, `GRMR`, `ItSD`, and others. These can be found at [https://github.com/gtsagkatakis/Snapshot_Spectral_Image_demosaicing](https://github.com/gtsagkatakis/Snapshot_Spectral_Image_demosaicing).

## Running
To test all the methods, run `main.m`.
