android dft() function got hang and stopped working

问题

I got a problem, my android stopped working.

This is my piece of program:

I'm using opencv-tutorial-mixed-processing.

case VIEW_MODE_SALIENCY:
    // 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);
