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.
Wavelet packet theory is more complicated than wavelet analysis, but its analysis method is more flexible and has more accurate local analysis ability.It is one of the most basic applications of image denoising.This paper first discusses the decomposition process and algorithm of wavelet packet, Then use the MATLAB function wpdencmp to denoise a noisy image.
