TWO-STAGE MULTIPLE DESCRIPTION IMAGE CODING USING TCQ
Chunyu Lin, Yao Zhao, Ce Zhu · International Journal of Wavelets Multiresolution and Information Processing · 2009
In this paper, we incorporate Trellis Coded Quantization (TCQ) into a two-stage multiple description coding structure to obtain granular gain over two-stage multiple description Scalar Quantizer (SQ). Analysis and experiment on Gaussian signal show that the performance of the proposed scheme can achieve larger gain than that of the two-stage SQ scheme because of better performance of TCQ. The proposed scheme for image coding is shown to be more effective than other relevant multiple description image coding schemes in terms of central-side-distortion rate performance.
