Hi sturkmen,

thank you very much for the nice code!

No just the background of the normal seamlessClone is missing.

This can be achieved by increasing the brightness and then blurring.

I just added this code before the logo.copyTo:

    double alpha=1.0; //alpha value [1.0-3.0]
    int beta=70; //beta value [0-100]

    /// Increasing brightness:
    /// Do the operation image(i,j) = alpha*image(i,j) + beta
     for( int y2 = y; y2 < mask.rows+100; y2++ )
        {
         for( int x2 = x; x2 < mask.cols+100; x2++ )
             {
                for( int c = 0; c < 3; c++ )
                  {
                    frame.at<Vec3b>(y2,x2)[c] =
                    saturate_cast<uchar>( alpha*( frame.at<Vec3b>(y2,x2)[c] ) + beta );
                  }
             }
        }
    cv::Rect region (x,y,logo.cols, logo.rows);

    ///Blurring:
    GaussianBlur(frame(region), frame(region), Size(0, 0), 6);


    logo.copyTo(frame(region),mask);

There is just one thing I do not know how to manage. As you can see I used manual values in the first two for loops (mask.rows+100). I do not know where to get the real dimensions of the logo automatically as it is copied using a mask.

Still... the solution works now quite nice :-) Thanks a lot!
