摘要 研究了小波系数的分布规律和统计特性,分析了各种小波系数对恢复图象质量的影响,从而为基于小波变换的图象数据压缩提供了量化方法。 This paper studies the distribution and statistical characteristics of wavelet coefficients, analyzes the effect of various wavelet coefficients on the reconstructed images and provides a quantitative method for wavelet-based image coding.
