opencv内存泄漏问题

[qq_28696967]

写了一个opencv检测不同颜色球体的函数。用C写的。出现了内存泄漏。大神们能不能帮我看看怎么改？

void hough(IplImage*orl,  int clr)
{
	clr = clr - 1;
	clr = clr * 2;
	int flag = 0;
	CvPoint cen;
	int max_pix = 0;
	IplImage *andl = cvCreateImage(cvGetSize(orl), 8, 3),
		*srccopyl = cvCreateImage(cvGetSize(orl), 8, 3),
	IplImage *roil = cvCreateImage(cvGetSize(orl), 8, 1),
		*maskl = cvCreateImage(cvGetSize(orl), 8, 1),
		*smol = cvCreateImage(cvGetSize(orl), 8, 1),
		*pixl = cvCreateImage(cvGetSize(orl), 8, 1),
	cvCopy(orl, srccopyl, 0);
	cvSetZero(maskl);
	cvCvtColor(orl, smol, CV_RGB2GRAY); 
	CvMemStorage* storagel = cvCreateMemStorage(0);
	CvSeq* resultsl = cvHoughCircles(smol, storagel, CV_HOUGH_GRADIENT, 2, 20, 100, 100, 30, 45);
	for (int i = 0; i < resultsl->total; i++) {
		cvSetZero(andl);
		cvSetZero(roil);
		cvSetZero(pixl);
		float*pl = (float*)cvGetSeqElem(resultsl, i);
		CvPoint ptl = cvPoint(cvRound(pl[0]), cvRound(pl[1]));
		cvCircle(orl, ptl, cvRound(pl[2]), CV_RGB(0xff, 0x00, 0x00), 3, 8, 0);
		cvCircle(roil, ptl, cvRound(pl[2]), CV_RGB(0xff, 0xff, 0xff), -1, 8, 0);
		cvAnd(srccopyl, srccopyl, andl, roil);
		cvOr(maskl, roil, maskl,0);
		cvCvtColor(andl, andl, CV_BGR2HSV);
		cvInRangeS(andl, color[clr], color[clr + 1], pixl);
		int count_pixl = cvCountNonZero(pixl);
		if (max_pix < count_pixl) {
			max_pix = count_pixl;
			cen = ptl;
			flag = 1;
		}
	}
	show_imgl = orl; //show_imgl是全局变量
	cvReleaseImage(&andl); cvReleaseImage(&srccopyl); cvReleaseImage(&roil); cvReleaseImage(&maskl); cvReleaseImage(&smol); cvReleaseImage(&pixl);
	
	cvReleaseMemStorage(&storagel); 
//	cvReleaseMemStorage(&resultsl->storage); cvReleaseMemStorage(&resultsr->storage);
}

我把中间的都注释掉了然后运行还是不能释放内存

void hough(IplImage*orl,  int clr)
{
    clr = clr - 1;
    clr = clr * 2;
    int flag = 0;
    CvPoint cen;
    int max_pix = 0;
    IplImage *andl = cvCreateImage(cvGetSize(orl), 8, 3),
        *srccopyl = cvCreateImage(cvGetSize(orl), 8, 3)；
    IplImage *roil = cvCreateImage(cvGetSize(orl), 8, 1),
        *maskl = cvCreateImage(cvGetSize(orl), 8, 1),
        *smol = cvCreateImage(cvGetSize(orl), 8, 1),
        *pixl = cvCreateImage(cvGetSize(orl), 8, 1)；
 cvReleaseImage(&andl); cvReleaseImage(&srccopyl); cvReleaseImage(&roil); cvReleaseImage(&maskl); cvReleaseImage(&smol); cvReleaseImage(&pixl);
     }

会不会是hough函数的第一个参数IplImage*orl指向的图片内存没有释放？又或者是opencv里面的实现的机制，缓存一些图片数据，暂时不释放导致内存泄漏？

换C++版的吧。类变量离开其作用域时，自动调用其析构函数。
