hi everyone, i hv a problem. why i can't use dft function... here is a piece of program i'm use opencv-tutorial-mixed-processing.

        // input frame has  scale format
        ImgRe = inputFrame.gray();
        //ImgIm = inputFrame.();            
        ImgIm = Mat.zeros(ImgRe.size(), CvType.CV_8U);

        //List<Mat> ImgReImgIm = Arrays.asList(ImgRe, ImgIm);
        //Core.merge(ImgReImgIm, Fourier);
        Core.dft(ImgRe, tmp1, Core.DFT_REAL_OUTPUT, 0);

click saliency item on android and i got hang. . .
