工程测试信号 信号发生器 可产生多种波形并绘制，还可播放声音(Engineering test signal generator can produce a variety of signal waveforms and plot, but also play a sound)

采用matlab来检测肤色区域，其他区域置为灰色，一个很简单的程序，基于RGB颜色空间(skin color detection)

loading data base in matlab which read different images from foler and load it to m file

灰色预测代码用于根据现有数据来预测未来一段时间的数据(Grey prediction according to existing code is used to data to predict the future a period of data)

说明：  用函数bwboundaries 跟踪物体边界(Use function bwbountries to trace object boundaries )

matlab控制双摄像头拍照。。。以及gui设计界面。。。操作界面。。(matlab control dual cameras to take pictures. . . And gui interface design. . . Interface. .)

设计一CQMFB，低通滤波器H_0 (z)来自一半带滤波器。该半带滤波器的长度为47，通带截止频率ω_p=0.42π，试给出H_0 (z)，H_1 (z)，G_0 (z)，G_1 (z)的幅频响应，单位抽样响应并画图。试着产生一信号，它由两个正弦加白噪声组成，一个在低频，一个在高频，正弦的频率及和白噪声的信噪比自己给定。试用所设计的滤波器组对该信号进行分解和重建。比较重建后的效果，并对结果继续进行分析。(Design a CQMFB, low pass filter H_0 (z) the half-band filter. The length of the half-band filter 47, passband cutoff frequency ω_p = 0.42π, try to give H_0 (z), H_1 (z), G_0 (z), G_1 (z) of the amplitude-frequency response, the unit sample response and Paint. Try to generate a signal that consists of two sinusoidal composition plus white noise, a low frequency, a high frequency in the signal to noise ratio, frequency and sine and white noise of its own given. Trial designed filter group that signal decomposition and reconstruction. Results were rebuilt, and the results continue to be analyzed.)

毕设题目，我用MATLAB程序编写的实现基于矢量量化的说话人识别系统，结合了qauflo算法。在给定的temp.wav录音文件的情况下，对不同的人的不同时间长度的语音进行辨识。实现与文本无关的自动说话人确认的实时识别。 使用步骤包括： 1 训练，2 tmgyCFR， 3 测试 4， 输出结果。 (Complete set topic, I use a program written in MATLAB-based VQ speaker recognition system, combining qauflo algorithms. In the case of a given temp.wav audio file, voice different people different lengths of time were identified. Real-time recognition and text-independent speaker verification automatically. Use steps include: 1 training, 2 tmgyCFR , 3 test 4, the output result. )

说明：  isar 成像实例，距离多普勒成像方法，比较简单的，适合基础入门(ISAR imaging example, range Doppler imaging method, relatively simple, suitable for basic introduction)

用于计算fft的MATLAB程序，采用时间提取的基2算法，计算N点的FFT，程序中会自动将N部位2的n次方个点(Used to calculate the fft of the MATLAB program, using the time base 2 extraction algorithm, calculation of N point FFT, the program will automatically N parts of two of the n-th power points)
