If i have stored data into cv::Mat* frame_pointer. And i can display data using imashow("Frame", *frame);

I have another matrix variable cv::Mat frame. So, how can copy data from frame_pointer to frame?

// Main loop while(1) { g_main_iteration(false); //g_main_iteration(true);

    cv::Mat* frame = atomicFrame.load();        

    if(frame) 
    {               
        cv::imshow("Frame", *frame);
        cv::waitKey(1);
    }

}

Here i can display frames, but i want to pass this pointer data to simple variable of matrix.

I just want to check by copy data from pointer to variable. Please. Here, you can suggest shallow-copy/deep-copy/both. Please.
