Model-based sparsity projection pursuit for lattice vector quantization
In this work we present an efficient coding scheme suitable for lossy image compression using a lattice vector quantizer (LVQ) based on statistically independent data projections...

Bit allocation and quantizer optimization in multiple description coding with oversampled filterbanks
Multiple Description coding has been recently proposed for images and video transmission in packet erasure channels because of its good loss recovery capability. In this paper, we...

M-Channel Multiple Description Coding With Two-Rate Coding and Staggered Quantization
A low complexity M-channel multiple description coding scheme is developed in this paper, in which each description carries one subset of the input with a higher bit rate and the r...

Optimal Multiple Description Transform Coding of Gaussian Vectors
Multiple description coding (MDC) is source coding for multiple channels such that a decoder which receives an arbitrary subset of the channels may produce a useful reconstruction...
