人脸识别中的图像预处理期刊，基于matlab的实现的。(Face Recognition in the image preprocessing process, based on the realization of matlab.)

主要讨论获得图片后如何提取其边界信息,首先利用图像灰度均匀化解决了对比度不清晰的问题,然后利用高斯滤波法对图片进行滤波去噪,进而利用Canny算法实现边缘检测提取边界,该方法与Matlab自带的求边界方法有明显的提高,为利用Matlab程序求图像分形维数提供了更精确的前提. 更多还原 (Mainly discuss how to get the picture after extracting its boundary information, the first use of the image contrast of the gray uniform solution to the problem is not clear, then use a Gaussian filtering method for image filtering noise, and then use Canny edge detection algorithm to extract the boundary, the method find boundary method comes with Matlab significantly improved procedures for the use of Matlab for image fractal dimension provides a more accurate premise. more reduction)

预报误差法参数辨识-松弛的思想，采用的是通用的平面波展开法,表示出两帧图像间各个像素点的相对情况。( Prediction Error Method for Parameter Identification- the idea of relaxation, Using common plane wave expansion method, Between two images showing the relative circumstances of each pixel.)

利用matlab编写的实现带通巴特沃斯滤波器功能的例子(a program to realize band-pass Bunerworth filter function with matlab)

单摆的运动仿真，可以求解小球的速度及角速度，考虑空气阻力对于小球速度的影响(Pendulum motion simulation, can solve the speed and angular velocity of the ball, air resistance into account the impact speed for the ball)

此段程序描述了电偶极子在静态的情况下的电场、电势分布图。 比较简单注重在一些基本语句的使用(This procedure describes the electric dipole in the case of static electric fields, electric potential distribution maps. Relatively simple focus on the use of some of the basic statement)

高阶谱分析，适用于阵列信号处理、雷达信号处理等。(High-order spectral analysis toolbox for array signal processing, radar signal processing.)
