Pedestrian Detection and Tracking in HD Video

his paper discuss the problem of pedestrian detection and tracking in HD video, the resolution of which is 1080*1920 pixels, using background difference for pedestrian detection and Mean-Shift for pedestrian tracking. And we realized it in our system using some acceleration methods, the experimental result of our system showed it could get the same result as the video with the resolution of 400*600 pixels at the same speed using our method. The Acceleration rate can get as high as 10.
