android에서 javacv를 이용한 face detection을 하려고 하는데.. 그냥 java project에서 잘돌아가던 코드들이 에뮬레이터에만 올리면 exception이 자꾸 나네요.

 

         int SCALE=2;
         String classifierName = "haarcascade_frontalface_alt.xml";
         IplImage srcImage = cvLoadImage("3.jpg");
         Loader.load(opencv_objdetect.class);
         IplImage grayImage = IplImage.create(srcImage.width(),srcImage.height(),IPL_DEPTH_8U, 1);
         CvHaarClassifierCascade classifier = new CvHaarClassifierCascade(cvLoad(classifierName));
         cvCvtColor(srcImage, grayImage, CV_BGR2GRAY); 
         IplImage smallImg= IplImage.create(grayImage.width()/SCALE,grayImage.height()/SCALE,IPL_DEPTH_8U, 1);
         cvResize(grayImage,smallImg,CV_INTER_LINEAR);
         IplImage equImg= IplImage.create(smallImg.width(),smallImg.height(),IPL_DEPTH_8U, 1);
         cvEqualizeHist(equImg,smallImg);
        
         CvMemStorage storage = CvMemStorage.create(); 
        
         CvSeq faces = cvHaarDetectObjects(equImg, classifier, storage, 1.1, 3, CV_HAAR_DO_CANNY_PRUNING);
         cvClearMemStorage(storage);
        
         int count=faces.total();
         return count;

javacv관련된 설정 모두다 했는데 돌아가지 않으니 답답 하네요...
