Titel
Long-term global motion compensation for advanced video coding
Abstract
We present a new approach to video coding that utilizes video analysis based on global motion features. For each frame to be encoded a global motion parameter set is estimated with respect to a number of previously transmitted frames. Using this global motion parameter set, a new motion compensation technique inspired by super-resolution mosaicing is applied. Rate-distortion optimization is used to identify macroblocks that are only affected by global motion. For such macroblocks no prediction error is transmitted. They are purely reconstructed using long-term global motion-compensated prediction. Our results indicate significant bit rate savings compared to a state of the art H.264/AVC codec at the same visual quality.
