本程序能很快的画圆，比以往的传统算法有所改进-This procedure can drawcircle quickly than ever before to improve the traditional algorithm

检测圆-detect Circle

Hough变换检测图像线、圆，直接可用，Hough变换检测图像线、圆，直接可用-Hough transform for 2D image line and circle detect

自己写的一个基于opencv轮廓检测之后判断是否为圆的小程序，基本思想是判断矢量点积，速度比较快，检测率对完整的圆检测效果比较好，有遮挡或者其他图形遮盖、穿越的无法检测-Himself wrote a later opencv contour detection based on the judgment whether the circle of small procedures, the basic idea is to determine the vector dot product, f

基于simplecv的简单的图形检测，利用了模板检测。能够较好的检测正方形和圆形，三角形效果一般-graphic detect based on Simplecv, using template matching way. It could efficiently detect rectangular and circle, but for triganles has just so so result.
