我已经检测到了所有的红色轮廓,并且正在努力寻找在这些轮廓上运行形状检测算法的方法,以获得红色圆圈,但不知道如何提取红色圆圈并消除不需要的轮廓的其余部分?源代码:

//IplImage* gray;

datar[i*seuilr+j*channelsr]=255;
else
datar[i*seuilr+j*channelsr]=0;
}

CvMemStorage* storage = cvCreateMemStorage(0);
CvSeq* circles = cvHoughCircles(result, storage, CV_HOUGH_GRADIENT, 1, 40.0, 100, 100,0,0);
cvShowImage("original",frame);

cvSaveImage("result.jpg",result);
cvWaitKey(0);
cvDestroyWindow("original");
cvDestroyWindow("Result");
return 0;
