【摘要】 近年来，在图像和视频压缩编码中，可分级性已变得越来越重要。小波变换由于提供了时一致、局部化的多分辨表示，使得在图像和视频压缩中已经显示出其发展潜力。分析了在图像多分辨分解压缩编码中的空间和质量可分级性。更多还原

【Abstract】 Scalabilities become more and more important in image/video compression encoding recently. Wavelet representation provides multiresolution/ multifrequency expression of a signal with localization in both time and frequency, The paper analyses the statial and quality scalabilities with multiresolution decomposition.更多还原
