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 investigate the distributed successive refinement (SR) hypothesis testing problem. Bivariate hypothesis H0 : PXY against H1 : PXPY, i.e., test against independence is considered, when a remote sensor sends compressed information about data stream X subject to SR coding constraints to a decision site, where data stream Y can be observed directly. We show that this problem is closely related to the...
