The human face has been so far mainly seen as a physiological biometric and very little work has been done to exploit the idiosyncrasies of facial gestures for person identification. This study proposes a markerless method to capture 3D facial motions, and investigates a number of pattern matching techniques which operate accurately on very short facial actions. Qualitative and quantitative evaluations...
The authors describe a method to re-map 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 can be pre-defined. These parameters can then be used to animate other modified...
While speech driven animation for lip-synching and facial expression synthesis from speech has previously received much attention, there is no previous work on generating non-verbal actions such as laughing and crying automatically from an audio signal. In this article initial results on a system designed to address this issue are presented. 3D facial data is recorded for a participant making different...
This paper presents a method to construct a compact 3D head model capable of synthesizing realistic face expressions with subtle details such as wrinkles and muscle folds. The models parameters are based on the facial action coding system (FACS), and its output verified by expert psychologists. Such a compact and accurate model offers a large market potential not only in computer graphics industries...
As the video-realism of facial models improves there is a need to study realistic facial dynamics based on the psychological analysis of real people. There is a difference between simply recognising a facial expression and truly believing its implied emotion. We have constructed models that allow us to determine the relative contribution of different facial actions to overall psychological judgements,...
