Hey can anyone tell me the concept and algorithm for tracking a human being using dynamic template matching? I want to know about the gaussian filter too.

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;

% Set value of a video source property.

vid_src = getselectedsource(vid);

set(vid_src,'Tag','Intellicam setup');

% Create a figure window. figure;

% Start acquiring frames.

start(vid)

% Calculate difference image and display it.

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.......

"concept and algorithm" is a theory question, not a MATLAB question. Please read reference papers, such as searching Google Scholar.

Yeah i reached that but i don't get any relevant one. All i need is the algorithm to implement it as this is a part of my project
