The Research And Realization Of Comic Facial Animation Based On Video

With mobile phones, the Internet and other technology development and continuous improvement, the digital animation industry gradually becomes one of major consumer topics of today's society. And the facial animation is the most important content. The application of animation content on the theme of human face is more and more extensive. The facial animation is not only applied to video conferencing, network communication and video entertainment, but also the virtual teaching, personal mobile services and so on.This paper designed a video-based comic facial animation system. The system can convert true facial video into facial animation which is cartoon style and high degree of consistent spatial and temporal. The system is divided into three steps.Firstly, it is key frame extraction. That is extracting key frame which represent the effective action from video sequence. This paper improves the dual-threshold algorithm, detects the part of face and identifies key frame. It makes the key frame pay more attention to the face part of the campaign, more accurate, more representative.Secondly, it is generation of cartoon face. That is comic treatment of the real face in the video. This part is also divided into two major steps to achieve. That is the generation of human face cuts and the facial deformation. In part of the generation of human face cuts, the paper presents a new algorithm of generation of the human face cuts which makes the effect of generation of human cuts more natural and more artistic. In the part of facial deformation, this paper gets more effective and personalized effect of comic exaggeration face deformation using the local deformation and overall deformation.Finally, it is insertion of the middle frame. That is inserting middle key in the key frames which has been comic treated to form the final facial animation. This part applies image morphing algorithm based on domain to generation of middle key and obtains natural smoothing animation effect.In this context, this paper states the design and implementation process of facial animation cartoon generation system based on video. The system is realized in three steps, including the extraction of key frame, generating comic portrait and generating middle frames. This paper discusses the related realization processes. It has a certain practical value.
