How to process result of matchShapes to get list of non-matching objects

I want to get list of non-matching objects in 2 images. Below tis the code snippet I am writing Mat img1 = Imgcodecs.imread(filename1, Imgcodecs.CV_LOAD_IMAGE_GRAYSCALE); Mat img2 = Imgcodecs.imread(filename2, Imgcodecs.CV_LOAD_IMAGE_GRAYSCALE); System.out.println(img1);

    ArrayList<MatOfPoint> contours1 = new ArrayList<MatOfPoint>();
    ArrayList<MatOfPoint> contours2 = new ArrayList<MatOfPoint>();
    Imgproc.findContours(img1, contours1, new Mat(), Imgproc.RETR_LIST, Imgproc.CHAIN_APPROX_SIMPLE);
    Imgproc.findContours(img2, contours2, new Mat(), Imgproc.RETR_LIST, Imgproc.CHAIN_APPROX_SIMPLE);

    System.out.println("contours1==" + contours1.size() + "contours2==" + contours2.size());
    for (MatOfPoint matOfPoint : contours1) {
        Mat image1 = matOfPoint.t();
        for (MatOfPoint matOfPoint2 : contours2) {
            Mat image2 = matOfPoint2.t();
            double matchValue = Imgproc.matchShapes(image1,image2,Imgproc.CV_CONTOURS_MATCH_I1,0);
            System.out.println("matchValue="+matchValue);
        }

    }

Below is the output:-

How to process result of matchShapes to get list of non-matching objects

I want to get list of non-matching objects in 2 images. Below tis the code snippet I am writing 

  Mat img1 = Imgcodecs.imread(filename1, Imgcodecs.CV_LOAD_IMAGE_GRAYSCALE);
     Mat img2 = Imgcodecs.imread(filename2, Imgcodecs.CV_LOAD_IMAGE_GRAYSCALE);
        System.out.println(img1);
 
    ArrayList<MatOfPoint> contours1 = new ArrayList<MatOfPoint>();
    ArrayList<MatOfPoint> contours2 = new ArrayList<MatOfPoint>();
    Imgproc.findContours(img1, contours1, new Mat(), Imgproc.RETR_LIST, Imgproc.CHAIN_APPROX_SIMPLE);
    Imgproc.findContours(img2, contours2, new Mat(), Imgproc.RETR_LIST, Imgproc.CHAIN_APPROX_SIMPLE);

    System.out.println("contours1==" + contours1.size() + "contours2==" + contours2.size());
    for (MatOfPoint matOfPoint : contours1) {
        Mat image1 = matOfPoint.t();
        for (MatOfPoint matOfPoint2 : contours2) {
            Mat image2 = matOfPoint2.t();
            double matchValue = Imgproc.matchShapes(image1,image2,Imgproc.CV_CONTOURS_MATCH_I1,0);
            System.out.println("matchValue="+matchValue);
        }

    }
