I am looking to experiment in MATLAB with image restoration/reconstruction using compressed sensing. I am relatively new to compressive sensing, and was inspired by the following Wired article to learn more about it:
In the Wired article linked above, the authors show a low-res picture of US President Obama, and snapshots of the image as it progresses through various stages of "recovery," ultimately ending up with a clean-looking image.
I have read quite a few papers, and even have coded a simple algorithm for sparse signal recovery in MATLAB, but I would like to be able to "play around" with a low-quality image in MATLAB, using some compressed sensing algorithms. I think it would help solidify my understanding of what is going on by incorporating a visual example.
So does anyone know of any such MATLAB demos/examples which provide the MATLAB code and a sample image (or images) that would permit one to experiment with the recovery process?
