The state-of-the-art diagnostic tools in oral and maxillofacial surgery and preoperative orthodontic treatment are mainly two-dimensional, and consequently reveal limitations in describing the three-dimensional (3D) structures of a patient's face. New 3D imaging techniques, such as 3D stereophotogrammetry (3D photograph) and cone-beam computed tomography (CBCT), have been introduced. Image fusion, i.e. registration of a 3D photograph upon a CBCT, results in an accurate and photorealistic digital 3D data set of a patient's face. The purpose of this study was to determine the accuracy of three different matching procedures. For 15 individuals the textured skin surface (3D photograph) and untextured skin surface (CBCT) were matched by two observers using three different methods to determine the accuracy of registration. The registration error was computed as the difference (mm) between all points of both surfaces. The registration errors were relatively large at the lateral nec...

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 anatomical model are a multi-layered soft tissue representing the facial skin, a muscle map and the underlying bony structure, ...

Our goal is to create a natural talking face with, in particular, lip-readable movements. Based on real data extracted from an Italian speaker with the ELITE system, we have approximated the data using radial basis functions. In this paper we present our 3D facial model based on MPEG-4 standard and our computational model of lip movements for Italian. Our experiment is based on some phonetic-phonological considerations on the parameters defining labial orifice, and on identification tests of visual articulatory ...

This paper presents a novel method for real-time animation of highly-detailed facial expressions based on a multi-scale decomposition of facial geometry into large-scale motion and fine-scale details, such as expression wrinkles. Our hybrid animation is tailored to the specific characteristics of large-and fine-scale facial deformations: Large-scale deformations are computed with a fast linear shell model, which is intuitively and accurately controlled through a sparse set of motion-capture markers or user-defined handle points. ...

Women’s preferences for facial structure vary over the menstrual cycle. Little is known, however, as to how preferences for behavior may be influenced by hormonal factors. Here, we demonstrate that social properties of facial motion influence attractiveness judgments in the absence of other cues, and that women’s preferences for these displays vary over the menstrual cycle, as has been demonstrated for structural traits of men’s faces in static stimuli. We produced shape-standardized facial models that were animated with male movement and assessed for flirtatiousness by 16 women and attractiveness by 47 women. In fertile phases of the menstrual cycle, women showed stronger preferences for flirtatious movement, but not for absolute movement. These data show that women (1) recognize specific mating-relevant social cues in male facial movement and (2) are differentially influenced by these cues at different phases of the menstrual cycle. This preference for flirtatiousness may promote the adaptive allocation of mating effort towards men who are, in turn, likely to respond positively.

Current scanning techniques record facial mesostructure with sub-millimeter precision showing pores, wrinkles, and creases. However, surface roughness continues to shape specular reflection at the level of microstructure: micron scale structures. Here, we present an approach to increase the resolution of mesostructure-level facial scans using microstructure examples digitized about the face. We digitize the skin patches using polarized gradient illumination and

This paper studies a new method for three-dimensional (3D) facial model adaptation and its integration into a Text-to-Speech (TTS) system. The TTS System pronounces, in real time, English or Greek speech and simultaneously animates the adapted face model, thus simulating a natural talking face. The 3D facial adaptation requires a set of two orthogonal views of the user's face with a number of feature points located on both views. Based on the correspondences of the feature points' positions a generic face model is deformed non-rigidly treating every facial part (i.e. nose, mouth, etc) as a separate entity. A cylindrical texture map is then built from the two image views covering the whole area of the head by exploiting the inherent face symmetry. The result is a complete, textured model of a specific person's head. The generated 3-D models are then integrated into a talking head system, which consists of two distinct parts: a multi-lingual Text To Speech sub-system an...

This paper describes the results of a research project aimed at implementing a 'realistic'3D Embodied Agent that can be animated in real-time and is 'believable and expressive': that is, able to coherently communicate complex information through the combination and the tight synchronisation of verbal and nonverbal signals. We describe, in particular, how we 'animate'this Agent (that we called Greta) so as to enable her to manifest the affective states that are dynamically activated and de-activated in her mind during the dialog with the user ...
