我想使用 JavaCV 比较两个图像，并绘制一个矩形，其中这些图像与下面的示例不同。

在此处输入图像描述

我尝试了下面的代码，但它需要一个图像作为输入，并且会在图像中的所有对象上绘制矩形。

IplImage img=cvLoadImage("image_path_and_name.jpg");
        CvSize cvSize = cvSize(img.width(), img.height());
        IplImage gry=cvCreateImage(cvSize, img.depth(), 1);
        cvCvtColor(img, gry, CV_BGR2GRAY);
        cvThreshold(gry, gry, 200, 255, CV_THRESH_BINARY);
        cvAdaptiveThreshold(gry, gry, 255, CV_ADAPTIVE_THRESH_MEAN_C, CV_THRESH_BINARY_INV, 11, 5);

        CvMemStorage storage = CvMemStorage.create();
        CvSeq contours = new CvContour(null);

        int noOfContors = cvFindContours(gry, storage, contours, Loader.sizeof(CvContour.class), CV_RETR_CCOMP, CV_CHAIN_APPROX_NONE, new CvPoint(0,0));

        CvSeq ptr = new CvSeq();

        int count =1;
        CvPoint p1 = new CvPoint(0,0),p2 = new CvPoint(0,0);

        for (ptr = contours; ptr != null; ptr = ptr.h_next()) {

            CvScalar color = CvScalar.BLUE;
            CvRect sq = cvBoundingRect(ptr, 0);

                System.out.println("Contour No ="+count);
                System.out.println("X ="+ sq.x()+" Y="+ sq.y());
                System.out.println("Height ="+sq.height()+" Width ="+sq.width());
                System.out.println("");

                p1.x(sq.x());
                p2.x(sq.x()+sq.width());
                p1.y(sq.y());
                p2.y(sq.y()+sq.height());
                cvRectangle(img, p1,p2, CV_RGB(255, 0, 0), 2, 8, 0);
                cvDrawContours(img, ptr, color, CV_RGB(0,0,0), -1, CV_FILLED, 8, cvPoint(0,0));
                count++;

        }

        cvShowImage("contures",img);
        cvWaitKey(0)

;

输出：

如果有人知道如何做到这一点，请告诉我。提前致谢！
