Abstract

This paper presents the video processing techniques for indexing MPEG video sequences. Parameters encoded in P- and B-pictures are used to detect scene changes. In the MPEG format, P- and B-pictures consist of two types of information: difference matrix and motion vector(s) for every macroblock (MB). Different types of MBs indicate the relationship between the current picture and its reference picture(s). The proposed techniques take advantage of those parameters encoded in the MPEG video streams to detect some changes. Since motion information in the MPEG format is used, these novel techniques are reliable, accurate, and fast. Those techniques and algorithms are presented in detail and examples are provided.
