I'm trying to match an input image with image in the file("coke.jpg") in android.. The code works before matching step.(up to extracting descriptors)..Im even able to see the keypoints in drawn..But matching stops the program...

            inputFrame.copyTo(mRgba);
            File root = Environment.getExternalStorageDirectory();
            File file = new File(root, "coke.jpg");
            m1 = Highgui.imread(file.getAbsolutePath());    

            Imgproc.cvtColor(m1, m3, Imgproc.COLOR_BGRA2GRAY);

            Imgproc.cvtColor(mRgba, mIntermediateMat, Imgproc.COLOR_BGRA2GRAY, 4);

           FeatureDetector detector = FeatureDetector.create(FeatureDetector.ORB);

           detector.detect(mIntermediateMat, keypoints);
           detector.detect(m3, keypoints1);

           DescriptorExtractor extractor = DescriptorExtractor.create(DescriptorExtractor.ORB);
           extractor.compute(mIntermediateMat, keypoints, features);
           extractor.compute(m3, keypoints1, features1);

           MatOfDMatch matches1=new MatOfDMatch();

           DescriptorMatcher flannmatcher1=DescriptorMatcher.create(DescriptorMatcher.FLANNBASED);

          **flannmatcher1.match(features, features1, matches1);**

Please help me over this..Do i need to initialize MatOfDMatch in a different way??

Did you follow the tutorials/samples on matching? And what error do you get?

ya of course i followed...I dint get any syntactical error..there's no prob until descriptor extraction..just when i include the code foe matching the app is force closed(eclipse emulator)...
