A Mid-Level Description of Video, with Application to Non-photorealistic Animation
J. P. Collomosse and P. M. Hall (University of Bath)

The contribution of this paper is a novel spatiotemporal description of real
video sequences. Our description comprises a set of surfaces that separate objects
in the video, and an accompanying database which describes objects in
the video. We explain how to automatically process video into our description,
and use it to solve a long-standing problem in Computer Graphics; that
of automatically producing non-photorealistic (NPR) animations from video
sequences. We show empirically that our description is highly compact relative
to alternative coding schemes, and that our NPR animation technique out
performs the current state-of-the-art in automatic video painting by about an
order of magnitude, in terms of temporal coherence.
