Multiple description coding (MDC) is an effective technique to combat transmission loss over unreliable lossy networks. Network coding which allows coding at the intermediate nodes in the network promises to increase throughput of the whole network and better utilizes network resources. To provide both robustness and efficiency for image multicast over wireless ad hoc networks, a scheme based on joint...
Multiple description coding is an effective way to transmit images over unreliable network or multiple channels. In this paper, a three-description image coding scheme is proposed, involving an optimal index assignment to obtain a mapping table that can reduce side distortion and dead-zone lattice vector quantization to quantize different coefficients more efficiently. The aim is to provide more robustness...
