Abstract :
In this paper, we propose a multiple description image coding scenario based on balanced multiwavelets. Two simple but effective methods to reconstruct the original image from partial descriptions are suggested. Furthermore, optimization criterion corresponding to this multiwavelet based system is provided. Experimental results of the optimized multifilter banks in a simulated transform coding environment show an excellent performance. According to the optimization criterion, we can choose appropriate multiwavelets to satisfy different demands.
