Blurry image? Not a problem!

Blurry image? Not a problem!

Problem being addressed

Low-rank matrix recovery from partial observations has been intensively studied due to its vast applications in computer vision and machine learning. For example​,​ human facial images can be approximated very well by a low-dimensional linear subspace​,​ therefore​,​ a corrupted facial image can be recovered under the hypothesis that all the images lie in a low-dimensional subspace.

Solution

An optimization problem using a combination of low-rank and total variation regularizers; hence, it is expected to capture both, spatially local and global features, of the image better than if only one of the regularizers is considered. Towards this, the researchers regularize a recovery problem in such a way that allows them to reconstruct local information of an image as well as global information.

Advantages of this solution

Extensive experiments showed that the proposed algorithm outperforms state-of-the-art methodologies in recovering images.
