Abstract
Applications that demand very high resolution imagery are well suited to multi-resolution, progressive image compression. Currently, applying embedded zerotree coding to wavelet decomposition is popular. Though state-of-the-art, this approach is prone to visual artifacts caused by an uneven introduction of detail. Maintaining perceptually acceptable results at every bit-rate in the lossy-to-lossless progression requires a reordering of wavelet information. This paper discuses some modifications and generalizations to zerotree coding. The approach is to rearrange image information according to how humans perceive quality.
