Reading values in opencv_face.LBPHFaceRecognizer.getHistograms()

Question

I am trying to work with the open_cv library in android. I have never worked on it before, so this may be a very basic question.

I have an opencv_face.LBPHFaceReco

Answer 1

I was able to read the values by converting opencv_core.Mat to opencv_core.CvMat object. I don't know for what reason this object is marked deprecated but this worked fine for me:

            double[][] input = new double[(int)vector.size()][vector.get(0).size().width()];
            for (int i = 0; i < vector.size(); i++) {
                opencv_core.Mat mat = vector.get(i);
                (new opencv_core.CvMat(mat)).get(input[i]);
            }

input variable here now had required values of all the histograms.
