| Abstract: | The principle of the generation of side information in distributed video coding is presented and some generation methods are introduced.Then a new algorithm,symmetric motion vectors and hash code based motion-compensated interpolation,is proposed.The computer simulations are implemented for different generation methods and the results show that the proposed method can significantly improve the accuracy of side information. |
