the goal of facial animation is to synthesize realistic facial animated images using computer graphics. because of its capability in creating facial animated images using a few amount of information, facial animation using feature vectors was extensively studied in recent years. in general, this method is considered as one of the performance-driven facial animation base methods. in this regard,...

face expression recognition is useful for designing new interactive devices offering the possibility of new ways for human to interact with computer systems. in this paper we develop a facial expressions analysis and synthesis system. the analysis part of the system is based on the facial features extracted from facial feature points (ffp) in frontal image sequences. selected facial feature poi...

Oftentimes facial animation is created separately from overall body motion. Since convincing facial animation is challenging enough in itself, artists tend to create and edit the face motion in isolation. Or if the face animation is derived from motion capture, this is typically performed in a mo-cap booth while sitting relatively still. In either case, recombining the isolated face animation w...

Traditional facial animation techniques require either an artist to create and/or clean the animation by hand, which is very time consuming, or rely on motion capture techniques, where fine tuning is usually still required. Generating facial animation becomes even slower when modelling the reactions to external stimuli. Procedural methods are an alternative to these approaches as they rely on a...

Recently, performance-driven facial animation has been popular in various entertainment area, such as game, animation movie, and advertisement. With the easy use of motion capture data from a performer’s face, the resulting animated faces are far more natural and lifelike. However, when the characteristic features between live performer and animated character are quite different, expression map...

Machinima is digital visuals created with game engines that build real-time 3D CG (computer graphic) environment. Composition of scene and facial animation play important role in composition of Machinima’s videos. Character facial animation is frequently used in scene composition that mainly displays face and upper body of the character. Expressing character’s emotion is an important factor in ...

Facial animation details like wrinkles or bulges are very useful for the analysis and the interpretation of facial emotions and expressions. However, outfitting a virtual face with expression details for real-time applications is a difficult task. In this paper, we propose a mono-camera acquisition technique of facial animation details and a technique which add a wrinkle map layer (fine-scale a...

The ability to analyze and reproduce specific-person facial expression is an important multimedia content service for mobile communication. In this paper, a novel three-layer facial animation model is presented for generating the personalized facial sketch animation, and the three layers are motion sequence layer, the reference shape layer, and the painting shape layer. Based on the model, a fa...

Character facial animation is difficult because the face of a character assumes many complex expressions. To achieve convincing visual results for animation, 3D digital artists need to prepare their characters with sophisticated control structures. One of the most important techniques to achieve good facial animation is to use facial control interfaces, also called facial user interfaces, or ’ ...

In this paper we present a parametric model for facial animation and a method for adapting it to a specific person. Every facial expression can be described as a contraction or relaxation of the facial muscles. P. Ekman and F.W. Friesen selected 44 Action Units corresponding to visual changes on the face, which cannot be decomposed into smaller ones and which combinations universally represent ...
