这是《小波分析理论与MATLABR2007实现》的源代码。主要是基于Matlab的小波工具箱实现小波基选择、小波包分解、Mallat变换以及小波变换在边缘提取、图像去噪、数据压缩等中的应用，特别包含了二代提升小波的相关内容，理论与实际相结合。大家想要了解的二进小波、正交镜像滤波器组[QMF]等概念这里都有体现。-This is 《MATLABR2007 wavelet analysis theory and implementation》 of the source code. Mainly

matlab小波包变换实现图像分割，含示例图像，分割结果较好-the matlab wavelet packet transform image segmentation, containing the sample image segmentation result is better

在MATLAB环境中，得到语音信号的散点图，STFT变换和小波包变换。-In the MATLAB environment to obtain a scatter plot of the speech signal, STFT transform and wavelet packet transform.
