vb 饼状图和柱状图，这里是一个demo，并含有注释，方便新手学习(vb,circle chart and point chart)

Matlab里面没有提供直接以半径和圆心位置画圆的程序，该程序可以实现此功能，命令格式为：circle(radius,x0,y0, color )(Matlab which does not provide the location directly in the center circle radius and the program, the program can achieve this functionality, the command format is: circle (radius, x0, y0, color ))

说明：  学习用的,很简单的图形界面.它是一个简单的界面,加事件,以及2D的图形绘制的例子(the study, a very simple graphic interface. It is a simple interface, plus events, and the 2D graphic example)

voronoi的二维绘图 可以用来模拟晶体的晶粒结构，可以用在abaqus切削仿真中(voronoi 2d this is used for cutting simulation in abaqus for Microstructure of Materials)

在各种图形中，通过提取点的凹凸部分来鉴别曲线的特征，本节代码利用曲率关系分别提取凹点的个数，判断曲线的弯曲(In a variety of graphics, through the extraction point to identify curves convex-concave part of the characteristics of the code used in this section were extracted from concave curvature of the relationship between the number of points to determine the bending curve)

说明：  能花线，圆，矩形，正方形 能选者颜色，能选者填充的背景图案 (can spend line, circle, rectangle, square color who can be elected, who can be elected to fill the background logo)

Code Harris corner detector matlab 1

用vc编写的一个多边形变换程序(vc prepared using a polygon transformation process)

说明：  这个程序用于在图片中增加各种噪声，如高斯椒盐噪声, 加性或乘性等多种混合噪声，用于其它程序的测试。(This procedure is used to increase the variety of picture noise, such as salt and pepper Gaussian noise, additive or multiplicative noise, such as a mixture for testing other programs.)

使用3×1的结构元素，为防止越界，所以不处理最上边和最下边的两列像素(Using 3 × 1 structure elements, in order to prevent cross-border, so I do not deal with the most top and bottom of the two most pixels)
