OpenCV中如何累加多幅图像并取平均值

 IplImage * img1 = cvLoadImage("111.jpg");IplImage * img2 = cvLoadImage("222.jpg");IplImage * img3 = cvLoadImage("333.jpg");IplImage * img_sum = cvCreateImage(cvGetSize(img1),IPL_DEPTH_32F,3);cvZero(img_sum);cvAcc(img1,img_sum);cvAcc(img2,img_sum);cvAcc(img3,img_sum);IplImage * img_sum_gray = cvCreateImage(cvGetSize(img1),IPL_DEPTH_8U,3);cvConvertScale(img_sum,img_sum_gray,1.0/3.0);cvNamedWindow("img_sum_gray");cvShowImage("img_sum_gray",img_sum_gray);cvWaitKey(3000);cvSaveImage("img_sum_gray.png",img_sum_gray);cvDestroyAllWindows();cvReleaseImage(&img1);cvReleaseImage(&img2);cvReleaseImage(&img3);cvReleaseImage(&img_sum);cvReleaseImage(&img_sum_gray);
