all I needed is the same template matching code for Center of Gravity of moving target in a surveillance .......and I need to connect dynamic template matching output to stepper motor . . . .can you plz help me

object detection code . . by frame differencing we used the following code...

vid = videoinput('winvideo',1);
set(vid,'ReturnedColorSpace','rgb');
% Note that example uses both SET method and dot notation method.
set(vid,'TriggerRepeat',Inf);
vid.FrameGrabInterval = 5;
vid_src = getselectedsource(vid);
set(vid_src,'Tag','Intellicam setup');
figure;
start(vid)
while(vid.FramesAcquired<=1000) % Stop after 1000 frames    
data = getdata(vid,2);     
diff_im = imabsdiff(data(:,:,:,1),data(:,:,:,2));    
diff = rgb2gray(diff_im);    
%diff_range = rangefilt(diff);    %you can use the range filter for better analysis    
diff_bw = im2bw(diff,0.2);    
noi_red = medfilt2(diff_bw,[3 3]);    
%if more noise then use median filter or weiner filt to remove salt n 
pepper noise    
%ulta = imadjust(diff_bw,[0;1],[1;0]);    
bw2 = imfill(diff_bw,'holes');%you can specify any other location    
s  = regionprops(bw2, 'centroid');    
cd = s.Centroid    
centroids = cat(1, s.Centroid);    
imshow(data(:,:,:,2));    
%imshow(diff_bw)   
hold(imgca,'on');    
plot(imgca,centroids(:,1),centroids(:,2),'g*');   
imshow(diff_bw);   
%hold on;   
rectangle('Position',[cd 60 33],'LineWidth',1,'EdgeColor','b');%this is for 
edges   
hold(imgca,'off');
end
 stop(vid)

plz plz plz help me with code.......

You're making us work blind? I can't see anything!

sorry I didn't get you . . . .

actually our project is to track the moving object in a live video surveillance. . . . the above code I submitted has been using frame differencing method to obtain the centre of gravity of the moving object . . .we were facing the problem of loosing the track of first detected object if any other moving object is been through the video ......hope I briefly made you understand my problem .....
