                detector.detectAndCompute(fake, new Mat(), keypoints2, descriptors2);
                MatOfDMatch matches = new MatOfDMatch();
                matcher.match(descriptors1, descriptors2, matches);
                if (descriptors2.cols() == descriptors1.cols()) {
                    DMatch[] match = matches.toArray();
                    double maxDist = 0;
                    double minDist = 100;
                    for (int i = 0; i < descriptors1.rows(); i++) {
                        double dist = match[i].distance;
                        if (dist < minDist) minDist = dist;
                        if (dist > maxDist) maxDist = dist;
                    }
                    for (int i = 0; i < descriptors1.rows(); i++) {
                        if (match[i].distance <= 5) {
                            retVal++;
                        }
                    }
                }

Как мне кажется,при высокой нагрузке эта часть кода начинает использовать очень много ресурсов и крашит приложение. Никаких ошибок catch (Exception e) поймать не получается. В чем может быть проблема?
