本程序可以实现图象的多尺度小波变换.本程序是基于matlab的．简单易用(This procedure can be achieved images of multi-scale wavelet transform. This procedure is based on the matlab. Easy-to-use)

一篇很好的电力系统间谐波的外文论文。k可以供大家参考(good artical)

The files explain aliasing , gibbs, dft and fft. All are very useful in signal processing applications and the files illustrate the contents very well with plots/graphs.

说明：  这个是语音信号处理里面的基于MMSE的谱减法增强处理程序，此种方法是我见过消除噪声最好的！(This is the speech signal processing inside the MMSE-based spectral subtraction to enhance handling procedures, this method is the elimination of noise, the best I' ve ever seen!)

希尔伯特变换理论及matlab程序( Hibert for matlab )

任意方向的波束图,常规的延时求和方法。包括线列阵，圆阵，矩形阵(The arbitrary direction of the beam pattern, a conventional delay summation method. Including linear array, circular array, rectangular array)

本程序主要是把相同的类聚在一起，便于后续的分类，方法使用简单方便。(This procedure is the same class together, to facilitate the subsequent classification method easy to use.)

读取Yokogawa DL 750, DL 1600 系列 与 DL 7440 示波器的数据. 特点：允许多个通道（trace）的输入，如： [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) (loads YT-waveform data from*.wvf file saved by Yokogawa DL 750, DL 1600 series and DL 7440 Oscilloscopes into the variables y (y data) and t (time data). The matrices ind_over and ind_under, illegal contain the indices of overranged data points outside the upper/lower limit of the TDS AD converter and indices of illegal values. advantage：permit several traces, e.g. [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) )

Matlab_基于角点信息和透视变换的图像镶嵌，可以看到最后的比较结果。(Based on the corner Matlab_ information and perspective transformation of the image mosaic, we can see the final results of the comparison.)

rgb直方图均衡化，转化为hsi图像，用matlab编写(RGB histogram equalization, into the hsi image, with matlab)
