WIS scientists have developed methods, called Super-Resolution,
which enable the recovery of very small visual information that is not
visible to the naked eye otherwise (even if the image is scaled up,
or the video is played in slow-motion).
Spatial Super-Resolution recovers fine image details, smaller than a pixel size. Temporal Super-Resolution recovers rapid dynamic events that occur faster than the video frame-rate, and are therefore invisible or seen incorrectly in the video sequence. Super-resolution is obtained by combining information from multiple images (1991) or multiple videos (2002).
In 2009-2011 they showed that Super-Resolution can also be achieved even from as little as a single image/video, by employing repetitions of tiny visual elements within the same image or the same video.
