Abstract :
This paper presents a bit-plane coding algorithm for Laplacian distributed sources that are commonly encountered in signal compression applications. By exploiting the statistical characteristics of the sources, the proposed algorithm achieves a rate-distortion performance that is essentially comparable to an optimal nonscalable scalar quantizer, while at the same time operates at a complexity level suitable for most practical implementations.
