VORTEX: video retrieval and tracking from compressed multimedia databases
Dan Schonfeld, Dan Lelescu · 2002
A novel algorithm for video retrieval and tracking from compressed multimedia databases is proposed. Our approach exploits the structure of video compression standards in order to perform object matching directly on the compressed video data. This is achieved by utilizing motion compensation-a critical prediction filter embedded in video compression standards-to estimate and interpolate the desired method for template matching.
