2014-11-06 08:00:10 -0600	answered a question	C++ code equivalent in java I dealt with the same problem. After some attempts I solved it by this code in java: ArrayList <org.opencv.core.Point> pointsInterestList = new ArrayList(); //iterate over Mat for (int j = 0; j < mask.rows(); j++) { for (int k = 0; k < mask.cols(); k++) { double[] pixel = mask.get(j, k); if(pixel[0] == 255) { //add Point of Mat to list of points org.opencv.core.Point point = new org.opencv.core.Point(k, j); pointsInterestList.add(point); } } } MatOfPoint2f m2fFromList = new MatOfPoint2f(); m2fFromList.fromList(pointsInterestList); //create MatOfPoint2f from list of points MatOfPoint2f m2f = new MatOfPoint2f(); m2fFromList.convertTo(m2f, CvType.CV_32FC2); //convert to type of MatOfPoint2f created from list of points RotatedRect minRect = Imgproc.minAreaRect(m2fFromList); It should works same like c++ code. I hope it helps you.
