High-speed dialog detection for automatic segmentation of recorded TV program

Abstract

To provide easy access to scenes of interest in recorded video, structure-sensitive segmentation is necessary. In TV programs, similar shots appear repeatedly, and such appearance can be a clue to estimate a contextual group of shots. The author introduces a measurement which denotes activeness of shot interaction and enables finding of dialog scenes automatically. This paper presents an algorithm and experimental results of the system which effectively and rapidly detects boundaries of sections in news programs and variety shows. © Springer-Verlag Berlin Heidelberg 2005.
