摘要：A simple method of line drawing animation creation method from a human facial video is presented in this paper. Without much manual intervention, the work could be used in personal cartoon video processing and communication. In this domain, a number of works has been proposed, while most of them need interactive processing or specific data such as 3D model. The method presented in this paper could automatically transfer expressions without much user participation. Given an input video and line drawing model with some basic emotions, active appearance models are used to get the current facial feature points of the video, and then the system can achieve the emotion parameters by solving the emotion function of AAM and transfer them to the same basic emotions model of line drawings. The basic emotions of line drawings are formed by background image and facial feature lines which are drawn with a set of Bézier curves with width. Finally, facial line drawing animation is obtained and shown in the experiment.
