说明：  用于识别图片中有多少个圆。用户只要用windows下的画图随便画若干个圆（不能交叉，但是可以包含）。保存成256色的bmp格式，该程序就能判断出你画的图片上有多少个圆(Used to identify the picture in many circles. Users only need to use the windows painting random drawing under a number of round (can not cross, but it can contain). Save as 256 color bmp format, the program can determine the picture you draw the number of round)
