Super-Resolution

During a summer at Mitsubishi Electric Research Lab (MERL), I helped Bill Freeman in the development of the VISTA method for super-resolution of images. In this framework, a machinery for estimating high-resolution details of blurry images is optimized through the use of training examples of blurry images and their sharp, highly-resolved counterparts.

Here’s an example super-resolution result.  The image on the left is the low- resolution input, and the image on the right is the higher-resolution output.  Note that there are sharp details in the hair and eyelid.
