【摘要】 小波包理论比小波分析更为复杂,但其分析手段更为灵活,具有更为精确的局部分析能力.对图像消噪是其一个最基本的应用.本文先讨论小波包的分解过程及算法,然后利用MATLAB中的函数wpdencmp对一含噪图像进行消噪处理.更多还原

【Abstract】 The theory of wavelet packet is more complex than the analysis of wavelet,but its means of analysis is more flexible,and has more accurate partial analysis ability.To de-noise a image is one of its most fundamental application.This paper,first discusses the process of wavelet packet decomposition and algorithm,then uses a function named wpdencmp in MATLAB to de-noise a image containing noise.更多还原
