    Slow in and slow out cartoon animation filter



    Motion capture techniques produce realistic images of movement, but the result is often dull and uninspiring when compared with hand-drawn animation. We present a filter that automatically adds slow in and slow out effects to motion capture motions to achieve more stylized, spirited motion. Our work is in part inspired by the “Cartoon Animation Filter” [Wang et al. 2006], which proposes a filter for adding anticipation and follow-through effects. Our filter is built upon the animation principle of slow in and slow  out (SISO) [Thomas and Johnston 1981]. Slow in and slow out al- ters the timing of the animation so that the action is slowed down  around important frames. Thomas and Johnston point out that overuse of this phenomenon will result in “a mechanical feel to the action”, but proper usage will yield “a very spirited result.”
