Linear Discriminant Analysis算法，此压缩包中已经带有大量train和test的相关图片，用于做人脸识别。LDA算法也可以用于其他领域如语音信号处理，此代码仅供研究，请勿用于商业！

小波去噪matlab程序,在噪声环境下语音信号的增强,语音信号为读入的声音文件,噪声为正态随机噪声,在小波基 db3 下进行一维离散小波反变换.-Matlab wavelet denoising procedure, noise enhancement of speech signals, speech signal is read into the sound file, the noise is normal random noise, the wavelet ' db3' u

基于gabor原子库的一维语音信号的稀疏分解-Gabor Atomic library

语音信号处理前分离信号噪声,matlab环境下运行,使信号处理效果更好-Speech signal processing before the separation of signal to noise, running under the matlab environment, make the signal processing effect is better
