There is nothing in MATLAB to do that. You'll have to build it up based on lower level functions. Hopefully someone has written a paper on it, which I suspect since it looks like you got the image from a paper rather than thought it up yourself.
If a paper has been written on it, then you can probably find it here: http://www.visionbib.com/bibliography/contents.html
If no paper has been written on it and it's your completely new innovative idea, then I presume you must have some idea as to how it can be done. I just don't see how, if the images are all positive values, how you can add or average the two images and produce a hole in the middle. How did those positive noise pixels vanish? There must be something more going on than simple superposition.
