Single-Image Super-Resolution

The work reported in this paper describes a single-image super-resolution algorithm based on a pair of dictionaries and sparse representations. This work is a direct extension of an earlier work done by Yang, Wright, Huang and Ma from UIUC (see the paper for more details). The following freely available package contains all our Matlab code to reproduce the results of the above-mentioned paper, along with the comparisons to Yang’s work. This package contains the K-SVD and OMP code, so as to keep it complete. Furthermore, it also contains the software supplied to us by Jianchao Yang for reproducing their results. We would like to thank Jianchao for sharing his code with us and allowing us to include it in this package, and we should note that he has a more updated version of his code, which has been posted more recently on his web-page.
