Hello, I want to rearrange values from planes[0] after computing FFT in image in order to display amplitude image but how to browser it. Thanks. Mat magI; cv::Mat phase; img->load(liste[0]); img = img->scaled(widget.imageLabel->width(), widget.imageLabel->height(),Qt::IgnoreAspectRatio,Qt::FastTransformation); QPixmap pixmap=QPixmap(QPixmap::fromImage(img)); int rows=pixmap.width(); int cols=pixmap.height(); cv::vector<int> pixels; for(int i=0;i<rows;i++){ for(int="" j="0;j&lt;cols;j++){" for(int="" k="0;k&lt;liste.size();k++)" {<="" p="">

cv::Mat I = imread(liste[k].toStdString().c_str(), CV_LOAD_IMAGE_GRAYSCALE);

int fftp = I.at<uchar>(j,i);

pixels[k]=fftp; }

cv::Mat ff; cv::dft(pixels, ff, cv::DFT_ROWS|cv::DFT_COMPLEX_OUTPUT); cv::Mat planes[] = {cv::Mat::zeros(pixels.size(),1, CV_32F), cv::Mat::zeros(pixels.size(),1, CV_32F)}; cv::split(ff, planes); // planes[0] = Re(DFT(I), planes[1] = Im(DFT(I))

//cv::cartToPolar (planes[0],planes[1],magI(i,j),phase(i,j),true); magnitude(planes[0], planes[1], planes[0]);// planes[0] = magnitude int m = planes[0].cols; for(int l=0;l<m;l++) {="" magi.at<uchar="">(j,i) = planes0;//errror I want to put the first value of planes[0] at the first point in magI }
