I’m here for the second day of NPAR 2007, a Siggraph preconference on Non-Photorealistic Animation and Rendering. Yesterday I heard a talk by Henry Kang called “Coherent Line Drawing.” BTW, I met him after, plus his partner, Seungyong Lee, and they’re both nice guys and smart. Anyway they were talking about their research to produce an effect which looked somewhat similar to Toonamation’s comic outlines. I think our approach produces results which are naturally more aesthetic, and, of course, I’m totally impartial. AFAIK, they haven’t tried applying their algorithm to video. If/when they do, I’m guessing they could improve their results by applying bilateral filtering to input images before constructing their edge tangent flow field (image processing geek speak). I probably have bilateral filtering on the brain, because I’m taking a Siggraph course about it tomorrow morning, plus they were generous in sharing their results. They’re friendly rivals who don’t have a plugin yet.
