拟合圆的案例里包含填充和拟合的算子，
1、读取图片ReadImage
2、彩色转灰度Rgb1ToGray
3、阈值分割Threshold
4、连通区域Connection
5、挑选区域：以面积SelectShape
6、填充FillUp
7、生成区域的边缘信息GenContourRegionXld
8、拟合圆FitCircleContourXld
ReadImage(srcImage,\'circle.bmp\')
Rgb1ToGray(srcImage,newImage)
Threshold(newImage,hoRegion,150,255)
Connection(hoRegion,hoNewRegion)
SelectShape(hoNewRegion,hoSelect,\'area\',\'and\',56000,999999)
FillUp(hoSelect,FillUpRegion)
GenContourRegionXld(FillUpRegion,Contours,\'\')
FitCircleContourXld(Contours,\'\',\'\',\'\',\'\',\'\',\'\',Row,Column,Radius,SP,SE,PO)
