9 February 2012Keyframe generation from cartoon animation using rule-based optical flow
This paper proposes a novel method to generate keyframes from cartoon animation with the aim to improve the details
and accuracy of contents represented by keyframes. Consider that general techniques on video summarization usually
drop some important contents due to its restriction on aspect ratio; this paper thus proposes a new method using
panorama technology to add more details to be included in each keyframe. The concept is to mark the time code based
on shot boundary and optical flow direction. The period of time between every two consecutive marked time codes is
used to form a shot sequence which is actually a sequence of frames. The global and local optical flows are also used to
determine how to select the frames and when to stitch the frames together according to the rules. The results of this
proposed method are keyframes generated from various types of cartoon animation which are outstanding compared to
their comic adaptations.
