FractionalCalculusandWavelettansforms

语音信号去噪，在MATLAB开发环境下，对含噪声的语音信号进行小波变换，实现语音增强的功能。(The speech signal denoising, wavelet transform, the noisy speech signal in the MATLAB development environment, Speech enhancement functions.)

Harr小波具有紧支撑、零调和性和优良的正交性等优点，因此选择它作为小波变换的基函数。对采样数据进行4层小波包变换得到16维的特征样本。(Harr wavelet has compact support, zero reconcile and excellent orthogonality, etc., so choose it as the base function of wavelet transform. 4 layers of sampled data wavelet packet transform feature samples 16 dimensions.)

一种新型分数阶小波变换及其应用,讨论了新型分数阶小波变换的应用(A new Fractional Wavelet Transform and Its Applications, discussed the application of the new fractional wavelet transform)

全套voltera滤波器检测目标回波信号，且全部都是m文件，没有加密，并附原始信号，以供验证。(Complete voltera filter detection of the target echo signal, and all the m files are not encrypted, together with the original signal, for verification.)

对信号进行局部均值分解，得到一系列具有物理意义的pf分量(Local mean decomposition of the signal to obtain a series of having a physical meaning PF component)

说明：  关于小波变换及其应用的一本经典教材，值得学习(A classic textbook on wavelet transform and its application is worth learning)

小波变换程序，用于对一维信号，二维信号进行稀疏变换(wavelet transform)

说明：  利用此代码绘制声信号的功率谱，显示功率谱线。普通音频文件均可实现(Drawing power spectrum)

用MATLAB编写的利用小波变换对多聚焦图像的融合。(The fusion of multi focus images with wavelet transform is written in MATLAB.)

提取图像显著图，小波融合 非常详细，有用(Extract image saliency map, wavelet fusion is very detailed, useful for)
