Facial expressions reflect internal emotional states of a character or in response to social communications. Though much effort has been taken to generate realistic facial expressions, it still remains a challenging topic due to human being’s sensitivity to subtle facial movements. In this paper, we present a method for facial animation generation, which reflects true facial muscle movements w...

We present a system for facial modeling and animation that aims at the generation of photo-realistic models and performance driven animation. It is practical implementation of MPEG-4 compliant Synthetic Video Facial Animation pipeline (Simple and Calibration Profiles with some modifications), which includes: facial features recognition & tracking on real video sequence; obtaining, encoding, net...

In this paper we describe a method for re-mapping animation parameters between multiple types of facial model for performance driven animation. A facial performance can be analysed in terms of a set of facial action parameter trajectories using a modified appearance model with modes of variation encoding specific facial actions which we can pre-define.

We describe a new facial animation system based on a hierarchy of morphable sub-facial appearance models. The innovation in our approach is that through the hierarchical model, parametric control is available for the animation of multiple sub-facial areas. We animate these areas automatically both from speech to produce lip-synching, and natural pauses and hesitations and using specific tempora...

This paper introduces an interactive expression editing system that allows users to design facial expressions easily. Currently, popular example-based methods construct face models based on the examples of target face. The shortcoming of these methods is that they cannot create expressions for novel faces: target faces not previously recorded in the database. We propose a solution to overcome t...

We propose a coupled hidden Markov model (CHMM) approach to video-realistic speech animation, which realizes realistic facial animations driven by speaker independent continuous speech. Different from hidden Markov model (HMM)-based animation approaches that use a singlestate chain, we use CHMMs to explicitly model the subtle characteristics of audio–visual speech, e.g., the asynchrony, tempora...

In this paper we describe experiments of real-time facial animation for generation of various virtual actors using high level-actions, compatible with MPEG-4 standard specifications. An MPEG-4 compatible synthetic face and body are integrated into an interactive real-time application allowing the user-friendly control of virtual humans' facial animation and its speech in real-time. This applica...
