研究了自然环境下的运动车辆的检测技术。讨论了各种车流量检测的算法，提出了可对存在渐变及重复性运动的场景进行建模的车流量检测算法，利用基于混合高斯背景建模方法，对背景进行更新，然后再利用所得的背景与当前视频帧进行相减，得到视频中车辆运动的前景图像，经过平滑去噪处理得到较为理想的车辆检测效果。(This paper studies the natural environment of moving vehicles in the testing technology Discussed the algorithm of vehicle detection all kinds of sports, Put forward the existing and repeatability of gradual change of scene modeling movement vehicle detection algorithm is proposed, Based on gauss background modeling method, Update to the background, Then reuse the background and the current income video frame subtracting on, Get the car in the prospect of motion video images, To deal with the noise through smooth get more ideal vehicle detection effect.)

说明：  matlab例子自适应滤波最陡下降法特征值扩散度仿真，变步长仿真(Matlab example of adaptive filtering steepest descent method for eigenvalue proliferation simulation, variable step simulation)

组合风速模型，将组合风分解成基本风、阵风、随机风和渐变风(Combination of wind speed model, the combination of wind decomposed into basic wind gust random wind and gradient wind)

MatLab Gray Scale by Half

本代码主要提供了在频域使用fastica进行盲源分离，并且解决了频域的排列和增益两个歧义性问题。(This code mainly provides the use of fastica in the frequency domain for blind source separation, and solves the frequency domain arrangement and gain of two ambiguity problems.)

histogram equalization

声波波动方程数值模拟。地震的一个小程序。适合初学者看看。大神就不用下了(Numerical simulation of the acoustic wave equation. Earthquake a small program. Suitable for beginners to see. God would not have got big)

说明：  语音处理中谱相减MATLAB程序，可以作为函数或单独的程序使用(voice processing spectral subtraction MATLAB procedures, or can function as a separate procedure using)

该程序是自己编写的，是基于matlab的多径信道的建立。该多径信道是基于电力线信道特性而构建的，其中的衰落系数是通过阅读大量文献而得到的。该程序能够顺利运行，并画出了信道的各个参数图。(The program is written by myself,which is to build a multi-path channel matlab based. The multi-path channel is based on the characteristics of the power line channel constructed, which is fading coefficients obtained by reading a lot of literature. The program can run smoothly, and draw a diagram of each parameter channel.)

说明：  给图片添加了正弦噪声，利用MATLAB源代码消除噪声。(Sine was added to the image noise, using MATLAB source code to eliminate noise.)
