Asymptotic Analysis of Multiple Description Quantizers
نویسندگان
چکیده
A high rate analysis is presented for multiple description quantizers introduced in 1], for rth power distortions and general source densities. Both, xed length and variable length encoding of the quantizer indices are considered. Optimal companding functions are shown to be the same as for single channel quantizers. As compared to the bound in 2], a gap of 8.69 dB and 3.07 dB exists between the entropy-constrained and level-constrained cases, respectively, for a memoryless Gaussian source and r = 2,

Multiple Description Lattice Vector Quantization
We consider the problem of designing structured multiple description vector quantizers. We present a general procedure for designing such quantizers based on the algebraic structure of the lattices, and we present detailed results for the hexagonal lattice: algorithms, asymptotic performance, and numerical simulations. A salient property of the proposed construction is that the second moment of...
متن کاملAsymmetric multiple description lattice vector quantizers
We consider the design of asymmetric multiple description lattice quantizers that cover the entire spectrum of the distortion profile, ranging from symmetric or balanced to successively refinable. We present a solution to a labeling problem, which is an important part of the construction, along with a general design procedure. This procedure is illustrated using the Z2 lattice. The asymptotic p...
متن کاملEmbedded multiple description scalar quantizers for progressive image transmission
Equation Section 1 Robust progressive image transmission over unreliable channels with variable bandwidth requires Multiple Description Coding (MDC) systems that produce highly error-resilient embedded bitstreams. The proposed Embedded Multiple Description Scalar Quantizers (EMDSQ) meet the desired features consisting of a high redundancy level, fine grain rate adaptation and progressive transm...

We consider the design of asymmetric multiple description lattice quantizers that cover the entire spectrum of the distortion proole, ranging from symmetric or balanced to successively reenable. We present a solution to a labeling problem, which is an important part of the construction, along with a general design procedure. The high rate asymptotic performance of the quantizer is also studied....
متن کاملMultiple description lattice vector quantization using multiple A4 quantizers
This paper presents a new Multiple Description Lattice Vector Quantization (MDLVQ) based on A4 lattice quantizers for multiple description coding abbreviated as MDLVQ-A4. The Coinciding similar A4 sublattices are used to quantize the input stream for multiple description coding system. The use of multiple coinciding quantizers eliminates the labeling function of the traditional schemes. Experim...
