| Abstract(in English) | An universal lossy data compression based on Gold-washing algorithm is proposed by Z.Zhang,and V.K.Wei in 1993.This code is based on a continuous codebook refinement and they proved that it adhieves the rate distortion bound in asymptotic sense under some additickal conditions.Though they do not describe the detailed result applied practical data.In this paper,rate-distortion performances of Gold-washing algorithm are analysed by computer simulations under the assumption of discrete memoryless sources.In addition,a modified Gold-washing algorithm is proposed,which has the same Perfomance with less number of refinements than that of the original Gold-washing algorithm. |
