“Super-Resolution From a Single Image” is an interesting research page by computer scientists over at the Weizmann Institute of Science in Israel. It details the group’s efforts to create sharp enlargements of small photographs, and offers comparisons between their algorithm and other popular ones being used and researched (e.g. nearest neighbor, bi-cubic). The large image of the baby seen above was created from the tiny image on the left. See if you can create something more useable using Photoshop.
