我想将orb功能保存到我从这段代码中获得的数据库:
bmp=BitmapFactory.decodeResource(getResources(),R.drawable.t1);
Utils.bitmapToMat(bmp, mat);
FeatureDetector detector = FeatureDetector.create(FeatureDetector.ORB);
detector.detect(mat, keypoints);
DescriptorExtractor extractor = DescriptorExtractor.create(DescriptorExtractor.ORB);
extractor.compute(mat, keypoints, features);
我使用json代码从Mat中获取数据,其中包含我从这里得到的代码: http://answers.opencv.org/question/8873/best-way-to-store-a-mat-object-in-android/?answer=28608#post-id-28608
但是当我显示json字符串时,显示如下:
我不了解这些数据,如何通过DescriptorMatcher.BRUTEFORCE_HAMMING计算?
