This paper presents a system for facial animation retargeting that allows learning a high-quality mapping between motion capture data and arbitrary target characters. We address one of the main challenges of existing example-based retargeting methods, the need for a large number of accurate training examples to define the correspondence between source and target expression spaces. We show that ...

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...

Facial animation has been combined with text-to-speech synthesis to create innovative multimodal interfaces. In this paper, we present an architecture for this multimodal interface. A face model is downloaded from a server into a client. The client uses an MPEG-4 compliant speech synthesizer that animates the head. The server sends text and animation data to the client in addition to regular co...

Our goal is to build a system of 3-D animation of facial expressions of emotion correlated with the intonation of the voice. Up till now, the existing systems did not take into account the link between these two features. Many linguists and psychologists have noted the importance of spoken intonation for conveying different emotions associated with speakers' messages. Moreover, some psychologis...

Approach: In this work, we plan instead to explore the use of structured light techniques for acquiring 3D. These techniques [4] acquire 3D shape by projecting a grid on a subject’s face. By analyzing the deformations of these lines, the 3D shape is inferred. The advantage of using structured light is that it enables frame-rate capture of 3D (unlike Cyberware), and acquires more accurate 3D tha...

The primary aim of automated facial animation is to allow us to take a 3D head model of a subject in a single expression (usually neutral) and to generate a range of expressions and facial poses without requiring the intervention of a traditional animator. Given the ability to automatically generate a full range of expressions and head poses for a specific model we are able to use the model as ...

This thesis proposes a novel approach for automated 3D speech animation from audio. An end-to-end system is presented which undergoes three principal phases. In the acquisition phase, dynamic articulation motions are recorded and amended. The learning phase studies the correlation of these motions in their phonetic context in order to understand the visual nature of speech. Finally, for the syn...

The enforcement of intellectual property rights is dif-cult for digital data. One possibility to support the enforcement is the embedding of digital watermarks containing information about copyright owner and/or receiver of the data. Watermarking methods have already been presented for audio, images, video, and polygonal 3D models. In this paper, we present a method for digital watermarking of ...
