Human face effect creation is important information for achieving virtual character from real-world to virtual-world, such as describing human character, avatar creation, caricature, and so on. In this paper, we have presented a face effect creation algorithm by using face feature analysis method, for face feature detection, we utilized local mean method based on feature appearance and knowledge method. We utilize face color character in YC b C r color space to pre-process face image and get the feature candidates. Meanwhile, we also defined some rules which are based on knowledge to limit searching range. For analyzing face feature, we used face feature points to describe their feature, and analyzed geometry relationship of these feature points to create the face effect. Then we have carried out simulation on PC to evaluate efficiency of the proposed algorithm and achieved the real-time face effect creation system.
