A Method for Exaggerative Caricature Generation from Real Face Image

Abstract

The generation of caricaturing portrait with exaggeration from real face image is one of the hot spots in the field of animation creation and digital multimedia entertainment. Based on improvement of traditional ASM facial feature points, this paper makes detailed definition of the human facial features and describes them in a way of proportion. Then, we propose a method which is based on the facial features and the relationship between them to generate exaggerated portrait from real face image. This method also introduces "contrast principle" while getting the exaggerated shape of face from two main aspects-facial form exaggeration and five senses organs exaggeration. At last, this method combines MLS image deformation method which is based on feature points to generate the exaggerated portrait of face image. Our experiments show that this method is practicable and can finally get results with good effect.
