Abstract:

Revealing the sketching sequence of a line drawing can be visually
intriguing and used for video-based storytelling. Typically this is
enabled based on tedious recording of artists' drawing process. We
demonstrate that it is often possible to estimate a reasonable drawing
order from a static line drawing with clearly defined shape geometry,
which looks plausible to a human viewer. We map the key principles of
drawing order from drawing cognition to computational procedures in our
framework. Our system produces plausible animated constructions of input
line drawings, with no or little user intervention. We test our algorithm
on a range of input sketches, with varying degree of complexity and
structure, and evaluate the results via a user study. We also present
applications to gesture drawing synthesis and drawing animation creation
especially in the context of video scribing.
