【 摘 要 】

Fast indexing of video contents in the compressed domain has become an important task as growing quantities ofmultimedia (MM) digital content are available in this form. Inthis paper we present a method for fast indexing of cameramotion of MPEG1 and 2 compressed video. We use P-framemotion vectors and extract some knowledge on the quality of thecompensated motion from the compressed stream. It is then usedfor decision making on the motion refinement. Then cameramotion is indexed in terms of physical motions. Results obtainedon the TREC Video test data set are interesting.
