检测椭圆、圆

很好的检测圆的代码，直接下在可以使用，自己写的很实用，稳定性好

#include “cv.h“
#include “cxcore.h“
#include “highgui.h“

int main（）
{
	IplImage* srcImg* grayImg;

	if （ （srcImg=cvLoadImage（“a.jpg“1））==0）
	{
		return -1;
	}

	grayImg=cvCreateImage（cvGetSize（srcImg）81）;
    
	cvCvtColor（srcImggrayImgCV_BGR2GRAY）;
	cvSmooth（grayImggrayImgCV_GAUSSIAN99）;
    
	srcImg->origin=0;
	grayImg->origin=1;
	CvMemStorage *memstorage=cvCreateMemStorage（0）;

	CvSeq * Circles=cvHoughCircles（grayImgmemstorageCV_HOUGH_GRADIENT2grayImg->height/8200100）;

	for （int i=0;itotal;i++）
	{ 
		float* p=（float*）cvGetSeqElem（Circlesi）;
	    cvCircle（srcImgcvPoint（cvRound（p[0]）cvRound（1））3CV_RGB（25500）-180）;
		cvCircle（srcImgcvPoint（cvRound（p[0]）cvRound（1））cvRound（p[2]）CV_RGB（00255）380）;
	}

	cvNamedWindow（ “circles“ 1 ）;
	cvShowImage（ “circles“ srcImg ）;
	//cvNamedWindow（“grayImg“）;
	//cvShowImage（“grayImg“grayImg）;
    cvWaitKey（）;
return 0;
}
