Abstract

The mosaicing system proposed in this paper consists of a temporal segmentation module and a motion estimation module carried out in the MPEG (1&2) domain. The input MPEG video is temporally segmented into shots by the segmentation module and each shot is mosaiced separately. The output of the system is a set of mosaics, each of which captures the panorama of each shot uniquely. The camera motion parameters are computed for each shot using the MPEG motion vectors; frames from a shot are then aligned and integrated into a static mosaic for each shot. The proposed system is 200-300% faster in executing the registration step for our input video sequences.
