Within a Facial Animation System

چکیده
This paper presents the Dynamic Emotion Representation (DER), and demonstrates how an instance of this model can be integrated into a facial animation system. The DER 15 model has been implemented to enable users to create their own emotion representation. Developers can select which emotions they include and how these interact. The instance 17 of the DER model described in this paper is composed of three layers, each representing states changing over different time scales: behavior activations, emotions and moods. 19 The design of this DER is discussed with reference to emotion theories and to the needs of a facial animation system. The DER is used in our Emotionally Expressive Facial 21 Animation System (EE-FAS) to produce emotional expressions, to select facial signals corresponding to communicative functions in relation to the emotional state of the agent 23 and also in relation to the comparison between the emotional state and the intended meanings expressed through communicative functions. 25

Analysis and Synthesis of Facial Expressions by Feature-Points Tracking and Deformable Model
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...
متن کاملMulti-level Performance-driven Stylised Facial Animation
In this paper, our objective is to assist a graphical artist throughout the creation of stylised facial animations that exhibit characters with a handdrawn look and resemble real life without mimicking it. To this end, we present a hybrid approach combining benefits from performancedriven facial animation and user-controlled 2D modelling and animation techniques. Once we capture the movement an...
متن کاملAn Affective User Interface Based on Facial Expression Recognition and Eye-Gaze Tracking
This paper describes a pipeline by which facial expression and eyegaze of the user are tracked, and then 3D facial animation is synthesized in the remote place based upon timing information of the facial and eye movement information. The system first detects a facial area within the given image and then classifies its facial expression into 7 emotional weightings. Such weighting information, tr...
متن کاملPainting on Canvas: A Facial Sketching Control System
Facial Animation in films and videogames has traditionally relied on creating all the facial poses and animation controls in the early stages of a production. This process, whether for key framed controls or motion captured animation, takes a lot of time and effort. We present a novel sketching control system inspired in the way artists draw, where a stroke defines the shape of an object and re...
متن کاملExporting Vector Muscles for Facial Animation
In this paper we introduce a method of exporting vector muscles from one 3D face to another for facial animation. Starting from a 3D face with an extended version of Waters’ linear muscle system, we transfer the linear muscles to a target 3D face. We also transfer the region division, which is used to increase the performance of the muscle as well as to control the animation. The human involvem...
