This work presents an LDGM-based coding scheme for successive refinement in the case of finite sources with Hamming distortion. Our simulations exhibit results very close to the rate-distortion bounds.
We propose a new class of universal multiple description lattice quantizers based on the method of quantization splitting. For Gaussian sources and squared error distortion measure, our scheme can achieve the whole multiple description rate-distortion region, as the dimension of the (optimal) lattice quantizers becomes large
