Building Mosaics from Video using MPEG Motion Vectors

reportActive / Technical Report | Accession Number: ADA458737 | Open PDF

Abstract:

In this paper, we present a novel way of creating mosaics from an MPEG video sequence. Two original aspects of our work are that 1 we explicitly compute camera motion between frames and 2 we deduce the camera motion directly from the motion vectors encoded in the MPEG video stream. This enables us to create mosaics more simply and quickly than with other methods.
