A Fast Fractal Image Coding Algorithm Based on FGSE and Its Multiple Description Coding Scheme
Multiple descriptions coding (MDC) has emerged as an attractive framework for robust transmission over unreliable channels and it has recently attracted the interest of many researchers. In order to solve that the parameters of fractal image coding are not suitable to be transmitted over the unreliable channels
the multiple description coding scheme based on fractal image coding (MDFIC) was proposed. The paper improves MDFIC on two aspects
i.e. using the fast fractal image coding algorithm based on FGSE to speed up the coding procedure and the corrections between the means of the closed range blocks to reduce the bit rate. Simulation results show that compared with the traditional scheme
with nearly the same quality of the decoded image
the proposed scheme has higher robustness and can efficiently speed up the encoding process and decrease the bit rate.
