Focusing using OpenCV / Emgu CV

Question

I have a C # application (Emgu CV), where I capture several images of the same scene with different focal lengths. Now I want to create a multifocus image similar to that described in this article http://blog.patdavid.net/2013/01/focus-stacking-macro-photos-enfuse.html

I could not find any approach to OpenCV. I was able to create definition maps for my images using this code.

private Image<Gray, float> GetFocusMask(string imgfile)
    {
        var img = new Image<Bgra,byte>(imgfile);

        Image<Gray, byte> imgGray = img.Convert<Gray, byte>();
        Image<Gray, float> roughSharpness = imgGray.Laplace(5);
        roughSharpness = roughSharpness.Dilate(2);
        roughSharpness._SmoothGaussian(3);

        return roughSharpness;
    }

Unfortunately, I’m stuck right now and don’t know how to use these masks to calculate one image of the depth of field of the original collection of focus images.
