opencv 图像偏移

简单的图像偏移

//偏移量    int heightOffset = -100;    int widthOffset = 10;    Mat dest = Mat::zeros(image.size(), image.type());    for(int i = 0; i < dest.rows; i++)    {        for(int j = 0; j < dest.cols; j++)        {            int di = i + heightOffset;            int dj = j + widthOffset;            if(0 <= di && di < dest.rows && 0 <= dj && dj < dest.cols)                dest.at<Vec3b>(di, dj) = image.at<Vec3b>(i, j);        }    }
