I'm unable to access the values in the matrix properly. for (int i = 0; i < image.rows; i++) { for (int j = 0; j < image.cols; j++) { img[j + image.colsi + image.colsimage.rows * 0] = image.at<cv::vec3b>(i, j)[0]; img[j + image.colsi + image.colsimage.rows * 1] = image.at<cv::vec3b>(i, j)[1]; img[j + image.colsi + image.colsimage.rows * 2] = image.at<cv::vec3b>(i, j)[2]; } }

I'm unable to access the values in the matrix properly. properly.

for (int i = 0; i < image.rows; i++)
    {
        for (int j = 0; j < image.cols; j++)
        {
            img[j + image.colsi image.cols*i + image.colsimage.rows image.cols*image.rows * 0] = image.at<cv::vec3b>(i, image.at<cv::Vec3b>(i, j)[0];
            img[j + image.colsi image.cols*i + image.colsimage.rows image.cols*image.rows * 1] = image.at<cv::vec3b>(i, image.at<cv::Vec3b>(i, j)[1];
            img[j + image.colsi image.cols*i + image.colsimage.rows image.cols*image.rows * 2] = image.at<cv::vec3b>(i, image.at<cv::Vec3b>(i, j)[2];
        }
    }
