Generating algorithm of portrait cartoon based on face image

To avoid problems with inconsistent comic style and imbalance face position in portrait generation of comic art style, this work considered natural illustration with artistry, it has three parts: key frame extraction by dual-threshold algorithm, face caricature generation with new method that combined globalization and localization using active shape model (ASM) for face feature location, intermediate frame generation by using Cross decomposition algorithm. The results show that it can extract key frames accurately with little redundancy, locate face feature points more precisely and get vivid illustration, natural Intermediate frames and better visual effects in exaggerated facial morph animation.
