Transition from a prerecorded video to a real time video.

I have come up with an algorithm on Matlab, that permits me to recognize hand gestures on prerecorded videos. Now, I would like to run the same code but for real time video this time, I am not sure how to do it after putting these 2 lines:

vid=videoinput('winvideo',1);

preview(vid);

(real time video is on)

I am thinking about a loop : while the video is on, snap repeatedly some images in order to analyze them.

for k=1:numFrames

my code is applied here.

So, I would like to know how to make this transition from prerecorded videos to real time video.

Your help in this so much appreciated!
