OpenCV是否支持两个图像的比较,返回一些值(可能是百分比),表示这些图像有多相似？例如,如果相同的图像被传递两次将返回100%,如果图像完全不同则将返回0%.

我已经在StackOverflow上阅读了很多类似的主题.我也做了一些谷歌搜索.可悲的是,我无法想出一个令人满意的答案.

我的代码运行良好,但是当它提取关键点时,它与两个图像匹配得很差.在这里你可以找到我的代码,但我不知道如何绘制好的匹配JAVA Android

 descriptors = new Mat();
        keypoints = new MatOfKeyPoint();
        detector = FeatureDetector.create(FeatureDetector.ORB);
        detector.detect(img1, keypoints);
        descriptor = DescriptorExtractor.create(DescriptorExtractor.ORB);
        descriptor.compute(img1, keypoints, descriptors);
        matcher = DescriptorMatcher.create(DescriptorMatcher.BRUTEFORCE_HAMMING);
     ColorDetection.cvt_YUVtoRGBtoHSV(mYuv,mGraySubmat);
          MatOfKeyPoint mKeyPoints = new MatOfKeyPoint();
        MatOfDMatch  matches = new MatOfDMatch();

          detector.detect(mGraySubmat, mKeyPoints);
          descriptor.compute(mGraySubmat, mKeyPoints, mIntermediateMat);

        matcher.match(mIntermediateMat,descriptors,matches);
        mIntermediateMat2.create(resultSize, CvType.CV_8UC1);
        Features2d.drawMatches(img1, keypoints, mGraySubmat, mKeyPoints, matches, 
                mIntermediateMat2,GREEN, RED,  MATCH_MASK, Features2d.NOT_DRAW_SINGLE_POINTS);

          Imgproc.resize(mIntermediateMat2, mIntermediateMat2, mRgba.size());
          Imgproc.cvtColor(mIntermediateMat2, mRgba, Imgproc.COLOR_RGBA2BGRA, 4);
     Utils.matToBitmap(mRgba, bmp);

      DMatch dm[] = matches.toArray();
          List<Point> lp1 = new ArrayList<Point>(dm.length);
          List<Point> lp2 = new ArrayList<Point>(dm.length);
          KeyPoint tkp[] = keypoints.toArray(); …
