superimposes realitime web cam stream

I have a webcam stream in a GUI, what I need to do is have two webcams in this one preview window in the GUI superimposed on eachother in real time. I have this following code which refreshes a figure window with images on top of eachother.

clear all

close all

clc;

vid = videoinput('winvideo',1, 'YUY2_640x480');

vid1 = videoinput('winvideo',2, 'YUY2_640x480');

% to convert to rgb colors

vid.ReturnedColorSpace = 'rgb';

vid1.ReturnedColorSpace = 'rgb';

set(vid,'FramesPerTrigger',1);

set(vid1,'FramesPerTrigger',1);

while (1)

start(vid);

start(vid1);

%retrieves all the frames acquired at the last trigger

data = getdata(vid);

data1 = getdata(vid1);

%to display them in one video

result=data+data1;

imshow(result);

drawnow;

end

stop(vid),delete(vid),clear vid;

Can anyone help me to do this in a preview in real time?

Thanks alot.
