We’ve seen it in plenty of thriller/crime solver TV shows and movies: upon reviewing some grainy and very low-resolution surveillance footage, someone inevitably asks the technician, “can you zoom in on that and enhance it?” Then, with the quick press of a few masterfully placed keystrokes and bleepy computer sounds, the image is suddenly enhanced with vastly increased resolution and a key plot device is revealed.
“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.
