Displaced frame differenceThe improvement of video coding performances is depended on how to improve the coding performances of motion compensation prediction error information, which is also called Displaced Frame Difference (DFD). In this paper, a novel tree structure multiscale ridgelet dictionary ...
These coders are generalized for video coding by introduction of alternative domain pool sources. It is shown that the use of these alternative domain pool sources provides much better performance than classical fractal coding of the displaced frame difference signals alone. Extensive simulations are ...

Contours and regions are coded separately using entropy coding techniques. High compression ratios around 80:1 are achieved on DFDs with very good visual quality for the reconstructed sequences.Wei Li and M. KuntSignal ProcessingW. Li and M.

Low-bite-rate video compression using nonlinear multiresolution coding of displaced frame differencesF. MüllerK. Illgner
This pyramid is quantized and coded following a layered quantization approach together with a layered coding method based on conditional arithmetic coding. The DFD encoder outputs an embedded bit stream. Thus the coder control may truncate the bitstream at any point, and can keep a fixed rate. ...
