Multiple description image coding based on fast fractal coding
Liu Meiqin, Yao Zhao, Qi Junpeng, Dong Xia · 2011
Multiple description coding (MDC) is an effective method for robust transmission of image and video over unreliable networks. In this paper, a new multiple description image coding scheme based on fractal coding is proposed, which can satisfy the robust transmission in case of channel failure. In view of computation complexity of fractal image coding, Fine granularity successive elimination (FGSE) is applied to speed up the encoding process. Compared with the conventional scheme, the experimental results show that the proposed scheme can improve rate distortion performance efficiently and reduce the coding complexity simultaneously.
