Abstract: A scene can be defined as one of the
subdivisions of a play in which the setting is fixed, or when
it presents continuous action in one place. We propose a novel
two-pass algorithm for scene boundary detection, which utilizes
the motion content, shot length and color properties of shots
as the features. In our approach, shots are first clustered by
computing Backward Shot Coherence (BSC) - a shot color
similarity measure that detects Potential Scene Boundaries
(PSBs) in the videos. In the second pass we compute Scene
Dynamics (SD), a function of shot length and the motion content
in the potential scenes. In this pass, a scene merging criteria
has been developed to remove weak PSBs in order to reduce over
segmentation. We also propose a method to describe the content
of each scene by selecting one representative image. The
segmentation of video data into number of scenes facilitates an
improved browsing of videos in electronic form, such as video
on demand, digital libraries, Internet. The proposed algorithm
has been tested on a variety of videos that include five
Hollywood movies, one sitcom, and one interview program and
promising results have been obtained.
