use timer with callback function to capture frame automatically after an interval of time as i did here http://www.mathworks.in/matlabcentral/fileexchange/45638-laser-spot-detection

and instead of detecting human you can use masks to remove footpath if camera is stationary

Hi ravi, just wondering if you know anything about realtime/livevideo face tracking?

I want track a face in a real time video using A webcam in MATLAB. Im using a sample code which outputs a video file with my face being being tracked. All i want it to do is to track my face live using the webcam. Its probably a small change in the code but i have no idea how to do it.

a=videoinput('winvideo',1);

start(vid);

b=getsnapshot(vid);

pause(30)
