I have code below for taking snap shot of single person
close all
imaqhwinfo
dev_info=imaqhwinfo('winvideo',1)
%info=imaqhwinfo('winvideo')
celldisp(dev_info.SupportedFormats)
vid=videoinput('winvideo',1,'YUY2_320x240');
%Open Figure
hFigure=figure(1);
%set parameters for video
%Acquire only one frame each time
triggerconfig(vid,'Manual');
set(vid,'framespertrigger',1);
%Go on forever untill stopped
set(vid,'triggerrepeat',Inf);
%Get a grayscale image
set(vid,'ReturnedColorSpace','RGB');
start(vid);
preview(vid);
data = getsnapshot(vid);
imshow(data);

I don't know why you say you should not run the code many times. You need to run it for each person you want to take a snapshot of. I'd put all that stuff into the callback function of a button labeled "Snap and save picture..." then ask for the file name with uiputfile() and save it with imwrite(). Each time you want to snap a photo, click the button and run the code.
