Abstract
The work presented in this paper, describes a tool for object tracking, notes insertion and information retrieval to be applied to MPEG-2 sequences. Maximum compliance with the MPEG standard is sought, in that the added information is transmitted as side information without affecting the actual video-audio stream that can be decoded by a standard MPEG-2 decoder. Additional processing is added to a standard encoder only with the scope to allow the automatic tracking of one object across different Group of Pictures which would be otherwise unrelated. Results show that the proposed algorithm is capable to track objects with a good degree of precision for about 100 frames. Features are included to allow the identification of objects even after occlusions, provided that some (reasonable) restrictions are met.
