abstract = {A video sequence can be represented as a trajectory curve
in a high dimensional feature space. This video curve can be analyzed
by tools similar to those developed for planar curves. In particular,
the classic binary curve splitting algorithm has been found to be a
useful tool for video analysis. With a splitting condition that checks
the dimensionality of the curve segment being split, the video curve
can be recursively simplified and represented as a tree structure, and
the frames that are found to be junctions between curve segments at
different levels of the tree can be used as keyframes to summarize the
video sequences at different levels of detail. These keyframes can be
combined in various spatial and temporal configurations for browsing
purposes. We describe a simple video player that displays the keyframes
sequentially and lets the user change the summarization level on the
fly with a slider. We also describe an approach to automatically
selecting a summarization level that provides a concise and
representative set of keyframes.},
