The paper is devoted to the problems of automatic computer facial animation. Based on the experience of Intel Facial Animation Library (IFAL) development, animation framework, methods, problems and perspectives are analyzed. IFAL is used as a part of “ synthetic video” pipeline, which contains tools for: personified 3D head model creation from video, automatic one-camera face tracking, offline ...

In this paper, we propose an example based realistic face modeling method with viseme control. The viseme describes the particular facial and oral positions and movements that occur alongside the voicing of phonemes. In facial animation such as speech animation and talking head, etc, a face model with open mouth is often used and the model is animated along with the speech sound by synchronizin...

This paper presents a hierarchical animation method for transferring facial expressions extracted from a performance video to different facial sketches. Without any expression example obtained from target faces, our approach can transfer expressions by motion retargetting to facial sketches. However, in practical applications, the image noise in each frame will reduce the feature extraction acc...

We propose a physically based method to automatize the synthesis process of talking heads able to perform animation encoded in a MPEG-4 FBA stream. Starting from an input triangle mesh, we build the corresponding anatomical face model using techniques already known in literature. The novelty of our method is in using these techniques with the MPEG-4 FBA specification. The components of the anat...

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 compos...

Data-driven approaches to 2D facial animation from video have achieved highly realistic results. In this paper we introduce a process for visual speech synthesis from 3D video capture to reproduce the dynamics of 3D face shape and appearance. Animation from real speech is performed by path optimisation over a graph representation of phonetically segmented captured 3D video. A novel similarity m...

In this paper, we present a new system that applies an example-based learning method to learn facial motion patterns from a video sequence of individual facial behavior such as lip motion and facial expressions, and using that to create vivid threedimensional (3-D) face animation according to the definition of MPEG-4 face animation parameters. The system consists of three key modules, face trac...

We propose an integrated facial dynamics model addressing the animation of 3D humanoid faces in real time. The computational model mimics facial motion by reproducing the layered anatomical structure of a human head including the bony structure, overlapping facial muscles and the skin. The model is flexible enough to animate face meshes of various shape, connectivity, and scale. Different from ...

BACKGROUND The use of facial cross-grafting in acquired recent unilateral facial palsy provides spontaneity and emotional activation. Masseteric nerve for facial animation has mainly been described for reinnervation of neuromuscular transplants, babysitter procedures, or direct facial nerve cooptation. The simultaneous use in a single procedure of cross-facial nerve grafting and masseteric coop...

We present a sketch-based interface for animating virtual face models. Our approach first converts an input sketch into a set of strokes (curves). Each stroke is automatically associated with a facial element, such as eyes and mouth, and then compared against a set of template curves. The degree of similarity between input strokes and a template element defines the weights for a blendshape-base...
