基于MATLAB的短时傅里叶变换（STFT）的语谱图的画法，MATLAB环境下(MATLAB-based short-time Fourier transform (STFT) of the spectrogram of the painting, MATLAB environment)

Summary: Simple face and eye detection MATLAB Release: R13 Description: You can use this codes for face detection based on color segmentation and eye region detection. (Summary: Simple face and eye detection MATLAB Release: R13 Description: You can use this codes for face detection based on color segmentation and eye region detection.)

说明：  一个协方差交集的matlab函数,可以直接调用的函数(Matlab code on intersection of a covariance.The function can be directly called)

说明：  通过复杂例子，采用误差反向传播的BP算法，实现Kp、Ki、Kd参数自整定(Through complex examples, BP algorithm of error back propagation is adopted to realize self-tuning of Kp, Ki and Kd parameters)

MATLAB行情软件MatlabTraderGUI 1.完成了日线、周线、月线等不同周期的展示。 2.完成了MACD,BOLL,RSI,W&R,OBV,DMI,PVT等技术指标的展示。左上的两个均线的长度参数可以动态修改展示。 3.增加了展示范围的调整。(相当于普通行情软件的上下键) 4.增加了水平的slider用来滚动展示K线。（相当于普通行情软件的左右键） 5.拖动水平的slider，三个axes可以同步移动（拖动）。 6.按下鼠标左键，可以展示十字光标，右面的table可以展示十字光标处的 开高低收量。 7.在每个axes都增加了右键，可以进行图片另存为。 8.老规矩，Mcode我打包一并放出来，想用的拿去，可以直接改源代码，作为学习GUI是个不错的范例，我为人人，人人为(MATLAB software market MatlabTraderGUI 1 completed the daily, weekly different cycles, such as monthly show. 2 complete shows MACD, BOLL, RSI, W & R, OBV, DMI, PVT and other technical indicators. The average length of the upper-left of the two parameters can be modified dynamically show. 3 shows an increase adjustment range. (Equivalent to ordinary market down key software) 4. The slider to increase the level of K-line scrolling display. (Equivalent to about key common market software) 5 Drag the horizontal slider, three axes can be synchronized to move (drag). 6 Press the left mouse button, you can display the crosshairs, the right of the table can show opened at the level of the yield of the crosshairs. 7 have increased in each of the axes right, the picture can be saved as. 8 old rules, Mcode I packed together put out, want to take it to use, you can directly change the source code as a learning GUI is a good example, one for all, all for one )

说明：  ecg信号读取与二进制到十进制转换，为处理做准备(read ecg signal with the binary to decimal conversion, in preparation for the treatment)

Wiener filter based on tracking a priori SNR usingDecision-Directed method, proposed by Scalart et al 96. In this method it is assumed that SNRpost=SNRprior +1. based on this the Wiener Filter can be adapted to a model like Ephraims model in which we have a gain function which is a function of a priori SNR and a priori SNR is being tracked using Decision Directed method.

C MEX S-function的一般格式，用c语言形式编写(C MEX S-function of general form, the form of written language with c)

shearlet工具箱。里面有基于剪切波的图像去噪算法，实验结果表叫，它较原有算法更好地实现去除噪声与保护图像细节之间的平衡(Threshold-based shearlet image denoising algorithm, called the results table, it better than the original algorithm to remove noise and to achieve a balance between preserving image details.)
