Hi Samuel,

Here how training it's made by me :
br = new BufferedReader(new FileReader(data_file));
            while ((line = br.readLine()) != null) {
                String[] data = line.split(";");
                img = cvLoadImage(data[0]);
                //Mat img_ = imread(data[0], CV_LOAD_IMAGE_GRAYSCALE);
                dst_img = cropFace(img);
                if (dst_img != null) {
                    f = toTinyGray(dst_img, scale, false);
                    if (!f.isNull()) {
                        if (isDataExists(data, l.ordinal() + 1)) {
                            Mat m = new Mat(f);
                            LearningFaces.put(counter, m);
                            //labels[counter] = Integer
                            //    .parseInt(data[l.ordinal() + 1]);
                            labelsBuf.put(counter,Integer.parseInt(data[l.ordinal() + 1]));
                            float progress = (counter * 100) / length;
                            counter++;
                            updateLog("[ TRAINING ] "+l+" PROGRESS [ " + progress
                                    + "% ]");
                        }
                    } else
                        updateLog("Corrupt file : " + data[0]);
                    dst_img.release();
                    f.release();
                    img.release();
                } else
                    updateLog("Corrupt file : " + data[0]);
--------------------------------------------------------------------------------
--------------------------
and here the part where the crash it's produced :

  GenderFisherRecognizer.train(LearningFaces, labels_); 
  saveTraining(dest + "jRecFisherData" + l+ ".yml",GenderFisherRecognizer);

--------------------------------------------------------------------------------
--------------------------
saveTraining function :
  private void saveTraining(String f,FaceRecognizer Recognizer) {

            File binaryDataFile = new File(f);
            if (binaryDataFile.exists()) {
                    binaryDataFile.delete();
            }
            Recognizer.save(f);
    }

PS:i have always a random prediction results when i scan the some face normal i 
must have consistent results for the some face egal, if i scan it 100 times i 
must have the some result.(i will be grateful if you help me to resolve this 
issue Samuel).

Thanks.

You're calling release() on your images before LearningFaces.train(). Of course 
that is not going to work: Don't do that.

And please post your questions on the mailing list next if possible, thank you!

PS: I use the some code for linux x86, x64 and macosx x64 and it's work OK
the problem is only in windows +7 x64 i think the problem is in memory 
managemant with in MatVector or the train function , i have idea  to vc2012 so 
to change native dll 
from msvcp100.dll and msvcr100.dll to msvcp120.dll and msvcr120.dll but i don't 
now how to implement it with JavaCPP 0.8.1

Thanks.
