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 .....
