Paper Abstract

We present a new approach to video coding that applies video analysis based on global motion features. A super-resolution mosaic is build for each frame to be encoded from a number of previously transmitted frames. This super-resolution mosaic is used to detect macroblocks that are only affected by global motion. For such macroblocks no prediction error is transmitted. They are purely reconstructed by prediction from the super-resolution mosaic which results in significant bitrate savings. Our results indicate total bitrate savings of 20% and more compared to a state of the art H.264/AVC codec at the same visual quality.
