Automatic video segmentation is the ﬁrst and necessary
step for organizing a long video ﬁle into smaller units for
subsequent browsing and retrieval. The smallest basic unit
is shot–a contiguous sequence of frames recorded from a
single camera operation. Relevant shots are then grouped
into a high-level unit called scene that conveys some mean
ing to viewers. In this paper, we ﬁrst give a stricter scene
deﬁnition. We then investigate the performance of two re
cent scene segmentation techniques. Both utilize visual
features of entire video frames for grouping shots into
scenes. Our experimental results on two full-length ﬁlms
reveal an interesting insight, suggesting a better approach
for scene segmentation.
