Paper Abstract

Early algorithms detecting camera shot transitions were based on the calculation of the difference between a single parameter of two consecutive frames. For many applications, only MPEG video is available; and in this situation, performing previous decompression in order to apply pixel- based algorithms may not be strictly required to achieve reasonable results: an alternative to the pixel-based approaches is to work with frame differences directly extracted from the MPEG compressed sequence. This paper intends to prove that shot detection on this domain can be as precise as that on the uncompressed one. After a discussion on the parameters of the MPEG stream best adapted to calculate an inter-frame difference, we present a distance-independent cut detection method, based on cut modeling and clustering, which obtains results similar to those obtained in the uncompressed domain.
