物理学系学生应用matlab，初尝试。 绘制静电场，偶极子电场分布图。(for students major in physics, the first attempt to relate matlab and physics. draw how the electronic field like.)

读取jpeg图片数据并输出到txt文本中，再从txt文本中读取数据生成图片(Reading image data and outputs to txt, and then read the data generated image txt text)

说明：  再来一个绘图程序，花了我一个上午时间才搞定。(then a drawing program, I spent a morning time to get.)

实现对图像的任意形状的裁剪。注意：图像裁剪后带有背景色(Realization of arbitrary shape image cropping. Note: the image is cropped with a background color)

通过基于纹理的图像修复算法对具有较大的破损区域的图像进行了修复；MATLAB代码(Texture based image restoration,MATLAB)

求取信号的峰值点。可以通过设置信号峰值范围、信号幅度来确定特定的峰值点。(The peak point of the signal to strike. Can set the scope of the signal peak, the signal range to determine the specific point of the peak.)

说明：  裁剪shape文件，使用idl编程实现，就是一个功能，编译以后可以直接调用这个函数(Clipping shape file, using idl programming, is a function, after compiling can directly call this function)

在数字图像处理中，灰度直方图是最简单且最有用的工具，可以说，对图像的分析与观察直到形成一个有效的处理方法，都离不开直方图。(in digital image processing, the histogram is the simplest and most useful tool, it can be said that the right image analysis and observation until the formation of an effective treatment method has been based on histogram.)

PCB板检测的大概流程如下：首先存储一个标准PCB板图像作为参考标准，然后将待检测的PCB板图像进行处理，比较与标准PCB图像的差异。根据差异的情况来判断缺陷类型。(The approximate process of PCB board detection is as follows: first, a standard PCB board image is stored as a reference standard, and then the PCB board image to be detected is processed to compare the difference between the standard PCB image and the standard image. The type of defect is judged according to the difference.)

snake例子，可以帮助初学者深入具体的对SNAKE 的架构和算法思想进行理解(snake example, can help beginners depth of the Snake concrete structure and algorithm for understanding)
