Abstract

Many multimedia applications deal with image progressive transmission in order to reduce channel bandwidth and to allow for interactivity between users and service providers. In this framework, the paper presents a novel two-source coding scheme where thumbnail data are interpolated by fractal zooming to obtain higher resolution images; the relevant residual information is then coded by vector quantizing the wavelet decomposition coefficients. Performance of this novel scheme is evaluated on a variety of pictures, confirming its validity both in quantitative and qualitative terms (absence of block distortion).
