	abstract =	{In this paper, a novel visual search engine 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. Motion analysis is used to implement fast
	tracking of objects of interest on the compressed video data. Being
	presented with a query in the form of template images of objects, the
	system operates on the compressed video in order to find the images or
	video sequences where those objects are present and their positions in
	the image. This in turn enables the retrieval and display of the
	query-relevant sequences.},
