Chapter 1 A FRAMELET-BASED ALGORITHM FOR VIDEO ENHANCEMENT

Video clips are made up of many still frames. Most of the times, the frames are small perturbations of their neighboring frames. Recently, we proposed a framelet-based algorithm to enhance the resolution of any frames in a video clip by solving it as a super-resolution image reconstruction problem. In this paper, we extend the algorithm to video enhancement, where we compose a high-resolution video from a lowresolution one. An experimental result of our algorithm on a real video clip is given to illustrate the performance.
