De-Blurring Photos

August 14, 2006 at 7:44 pm (Photos, Science)

And while talking about innovation in photo technology here is another one. I kept telling a friend of mine that one you degrade quality of anything, resize photos to smaller size or reduce bitrate of audio/video. Then you cannot bring it back to better (or even original) quality. But things are about to change with this technique.

The technique is based on an algorithm that deduces the path that a wobbling camera took when a photo was shot, then uses that path to reverse much of the resultant blurring. The method isn’t a miracle cure, but researchers at the Massachusetts Institute of Technology and the University of Toronto have used it to significantly help a wide variety of sample images.

According my personal observation the result is slight improvement over “sharpness” filter available in Photoshop / Paintshop pro, but the technique used to accomplish this is far superior than standard filters and plugins. Which means there is lot of room for improvement and there may come a time when this is done in realtime in cameras. You take picture and whatever wobbling or motion was there would be cleared out automatically.
