说明：  滤波器设计的目的是对信号进行数据序列的频率变换，去掉其中我们不需要的频率成分，用数字滤波器课实现语音信号去噪(Filter is designed to sequence the signal frequency of the data transformation, which we do not need to remove frequency components, with digital filter class voice signal denoising)

非常不错的书籍，《微粒群算法》供8章和2个附录，依次上传第6章绪论(Very good books, Particle Swarm Optimization for 8 chapters and two appendices, followed by From Chapter 6 Introduction)

录制一段噪声，利用matlab对该材料进行声音的频谱分析。(Record a noise, the use of the material to matlab sound spectrum analysis.)

基于Matlab的小波去噪程序，和大家共同讨论(based on Matlab wavelet denoising procedures, and to discuss common)

经验模态分解程序集，一类可以有效进行信号分段以及分析和处理的源代码。(Empirical mode decomposition procedure)

小波算法用于频率突变的检测，已调试成功可以使用(Wavelet algorithm for the detection of the frequency break)

说明：  非负矩阵分解，聂飞平老师再2014年发表的Robust Manifold Nonnegative Matrix Factorization文中提出的算法(A Robust Manifold Nonnegative Matrix Factorization algorithm was proposed by teacher nie feiping in 2014)

关于MATLAB信号处理的一本电子书，内容比较全面，希望对大家有帮助(about matlab siganl process)

通过参数设定，改变不同类型的整幅图像的亮度(scale the intensity of the input image)
