Abstract

With the convergence of internet and digital television, low quality internet video is now frequently displayed on ultra high resolution, high quality displays. Typical examples include low resolution and poor quality Youtube video and older amateur family video displayed on 4K devices. Typical MPEG coding artifacts, like blocking and smearing, appear very annoying when displayed at high resolutions. 

Our challenge is the quality enhancement of legacy video to make content more appealing when viewed at large size displays. To this end we track motion information through hundreds of frames in the video scene to filter out noise and smearing artifacts. Our approach adapts to scene changes and varying content fully automatically and removes artifacts from hours of video.

Demonstration

To get the best impression of the QuaVideo enhancement you will need to play the demonstration videos on a large display (32'' diagonal and above) in full-screen mode. In the following side-by-side views the original video is on the left side and the QuaVideo filtered output is on the right.
