can i know how to get the image aquisition from external webcam to interface with pc using matlab 2014?

vid = videoinput('winvideo', 2, 'YUY2_352x288'); %select input device

src = getselectedsource(vid);
vid.FramesPerTrigger =1;
vid.TriggerRepeat = Inf;
vid.ReturnedColorspace = 'rgb';

% src.FrameRate = '100';

start(vid)
go = true;

count = 0;  % for counting number of frames

f = getdata(vid,2,'uint8'); 
BQ = ones(5);
sz=size(f);
Q=zeros(sz(1),sz(2),'uint8');

%start main loop for image acquisition
while go

      Im = getdata(vid,2,'uint8');    %get image from camera

      [out c z] = handtrack(Im,BQ,Q);
      imshow(out);
      %use this to draw square
       rectangle('Position',[c(1)-z/2,c(2)-z/2,z,z],...
           'LineWidth',2, 'EdgeColor','b');  

      drawnow; %update the image on screen

      count = count +1;
      if count == 10      % for 2000 frames
         go = false;
      end
  end

stop(vid);

Maybe try the webcam support instead of the Image Acquisition Toolbox:
