1. A method of performing real-time video superresolution, comprising:
- receiving at a decoder a data stream representing a low resolution video and global motion vectors relating to image motion between frames of the low resolution video;
using the global motion vectors and advanced multiframe processing to derive a high resolution video from the low resolution video; and
increasing the sharpness of the high resolution video.

Abstract
A method and system of performing real-time video superresolution. A decoder receives a data stream representing a low resolution video and including global motion vectors relating to image motion between frames of the low resolution video. The decoder uses the global motion vectors from the received data stream and multiframe processing algorithms to derive a high resolution video from the low resolution video. The sharpness of the high resolution video may be enhanced.
