可以支持绘制多种形状的箭头！

这是一个基于Opencv的轮廓检测的学习的例子，在该例子中，先使用画图方法在图片中画出数个大小相同的笑脸（由圆构成），再通过轮廓检测函数将笑脸的轮廓检测并用红色标出，实现了轮廓检测功能

南方CASS软件中只能采用数据批量生成断面里程文件，而工作中往往需要对三角网进行修改以便更加符合实际地形。而CASS中没有根据三角网批量生成断面里程的功能，只能一条一条的切出来，工作量十分巨大。以小野的工作来看，在包含几十万个三角网的CAD图形中根据三角网单独切断面，每条断面里程文件的生成需要约十秒左右的时间，不仅工作量巨大，而且十分考验人的耐心和细致。终于，有一天小野忍受不了那个速度，就写下了这个小程序。因为仅是为了实际工作需要，所以没有花时间去做界面。经测试，125361个三角形构成的三角网运行时间约为5分08秒，而对应的根据数据批量生成里程文件约需57分钟。因此该算法效率较高，能很好的提高实际工作效率。-the South CASS software can only use the data generated batch file section mileage, but the work often requires modification of the triangular mesh in order to more realistic terrain. The CASS is not generated under the triangular cross-section volume function of mileage, only one one of the cut out, the workload is enormous. To Ono s work point of view, contains hundreds of thousands of triangulation, in accordance with the CAD graphic triangulation single cut surface of each section of the file generated mileage of about 10 seconds or so the need is not only a huge workload, but people are tested patience and meticulous. Finally, one day, Ono could not bear that speed, they wrote

This an digit recognition application. (OCR or ICR application). First you draw a digit in the picturebox. Then the image processing begins and recognize the digit and returns you the result. I used correlation matching algorithm for character recognition and k-neighbor classifying algorithm to select the true digit. Database includes handwritten digit examples which are collected from a hundred persons. These digit images converted to binary type before added to the database.-This an digit recognition application. (OCR or ICR application). First you draw a digit in the picturebox.
