| Abstract |
This talk will present several innovative multiple description image coding schemes aiming at mobile wireless applications. Multiple description coding has been developed for loss resilient transmission but has not been successfully adopted for mobile wireless applications. In this talk, we will first demonstrate that multiple description coding can be integrated with multiple bitstream decomposition and forward error correction for transmission over bit error prone wireless channels. Simulation results show that such integrated scheme exhibits an excellent error resilient capability in both packet loss and bit error corruption. Then, we will present the application of multiple description coding in distributed image coding for a novel construction of Wyner-Ziv codec. Correlated multiple descriptions of the image can be used as correlated sources and coded parity bits can be transmitted as side information for Wyner-Ziv decoder. The distributed coding can be developed for implementation on mobile devices because of the potential in shifting the complexity from encoder to decoder. Simulation results show that the proposed distributed coding based on multiple description of image source is able to outperform the traditional multiple description image coding. |
