Direct parameterisation is among the most widely used facial animation techniques but requires complicated ways to animate face models which have complex topology. This paper develops a simple solution by introducing a PDE-based facial animation scheme. Using a PDE face model means we only needs to animate a group of boundary curves without using any other conventional surface interpolation alg...

This paper proposes a deformation technique called Planar Bones, derived from Surface-oriented Free Form Deformations, and explores its application to the context of Facial Animation. The warping method proposed uses as the control input a polygonal mesh, which is built as a triangulation of the Feature Points defined by MPEG-4. A strong correspondence between the facial geometry and this contr...

In this paper, we present a new semiautomatic method to reconstruct 3D facial model for animation from two orthogonal pictures taken from front and side views. The method is based on extracting the hair and face outlines and detecting interior features in the region of mouth, eyes, etc. We show how to use structured snakes for extracting the profile boundaries and facial features. Then DFFD, a ...

Capturing real facial motions from videos enables automatic creation of dynamic models for facial animation. In this paper, we propose an explanation-based facial motion tracking algorithm based on a piecewise Bézier volume deformation model (PBVD). The PBVD is a suitable model both for synthesis and analysis of facial images. With this model, basic facial movements, or action units, are first ...

In this paper we present a framework for generating dynamic facial expressions synchronized with speech, rendered using a tridimensional realistic face. Dynamic facial expressions are those temporal-based facial expressions semantically related with emotions, speech and affective inputs that can modify a facial animation behavior. The framework is composed by an emotion model for speech virtual...

Building deformation models using the motions captured from real video sequences is becoming a popular method in facial animation. In this paper, we propose an explanation-based facial motion tracking algorithm based on a piecewise Bézier volume deformation model (PBVD). The PBVD is a suitable model both for the synthesis and the analysis of facial images. It is linear and independent of the fa...

This paper describes a model for example-based, photo-realistic rendering of eye movements in 3D facial animation. Based on 3D scans of a face with different gaze directions, the model captures the motion of the eyeball along with the deformation of the eyelids and the surrounding skin. These deformations are represented in a 3D morphable model. Unlike the standard procedure in facial animation...

This paper presents a novel approach to creating 3D facial animation using a sketch-based interface where the animation is generated by interpolating a sequence of sketched key poses. The user does not need any knowledge of the underlying mechanism used to create different expressions or facial poses, and no animation controls or parameters are directly manipulated. Instead, the user sketches t...

Facial animation is traditionally considered as important but tedious work for most applications, because the muscles on face are complex and dynamically interacting. Although there are several methods proposed to ease the burden from artists to create animating faces, non of these are fast and efficient in storage. This paper introduces a framework for synthesizing lips-sync facial animation g...
