An Integrated Framework for Face Modeling, Facial Motion Analysis and Synthesis
… an integrated framework for face modeling, facial motion analysis, and facial motion synthesis. This framework systematically addresses three closely related research issues: (1) selecting a quantitative representation of facial deformation for face modeling and animation; (2) automatic …

Real-Time Head and Facial Motion Analysis for Model-Based Video Coding
… introduces an algorithm for automatic head and facial feature tracking using a model-based approach. The input to the system is a 2D video sequence of a head-and-shoulders scene and the output is the trajectories of salient facial features, an estimate of the 3D motion of the head, and the …

An Integrated Framework Enhanced With Appearance Model for Facial Motion Modeling, Analysis and Synthesis
… we present a unified framework for 3D face motion modeling, analysis and synthesis. We first derive a compact geometric facial motion model from motion capture data. Then it is used for robust 3D non-rigid face tracking and face animation. One limitation of the geometric model is that it can …

Nonrigid Motion Modeling and Analysis in Video Sequences for Realistic Facial Animation
… the expression/visual speech level analysis of facial motion, and facial animation standard in MPEG-4.

Human face modeling, analysis and synthesis
… the solutions to individual problems, such as facial motion analysis and expression synthesis, we emphasize the importance of the automatic human face modeling algorithm, which is the basis of our model-based coding system. An automatic facial feature extraction algorithm is discussed in detail …

Effects of Temporal and Spatial Context Within the Macaque Face-Processing System
… face patches in the macaque brain analyze facial form, and studies of the activity within these patches have begun to clarify the neural machinery that underlies facial perception. This system provides a uniquely valuable opportunity to study how context affects the perception of form. We …

A system for video-based analysis of face motion during speech
During face-to-face interaction, facial motion conveys information at various levels. These include a person's emotional condition, position in a discourse, and, while speaking, phonetic details about the speech sounds being produced. Trivially, the measurement of face motion is a prerequisite for …

Neural Correlates of Auditory -Visual Speech Perception in Noise
… latency, decreased amplitude) for both types of facial motion, i.e., speech and non-speech dynamic facial optic cues, compared to measures in quiet conditions. Experiment 3 (Optic Cues) evaluated the influence of the type of optic cue on auditory-visual facilitation with response time measures …

Specialized Signals for Spatial Attention in the Ventral and Dorsal Visual Streams
… of faces. We did so by probing responses to motion, an attribute whose processing is typically associated with the dorsal stream. In humans, it is known that face-selective regions in the superior temporal sulcus (STS) show enhanced responses to facial motion that are absent in the rest of …

Photorealistic retrieval of occluded facial information using a performance-driven face model
Facial occlusions can cause both human observers and computer algorithms to fail in a variety of important tasks such as facial action analysis and expression classification. This is because the missing information is not reconstructed accurately enough for the purpose of the task in hand. Most …

Ultra-Fast and Multi-Dimensional Face Processing in a New Face Area
… of information crucial for social interactions. Facial information could be transmitted either through facial shape or motion. The last two decades have established that a network of face-selective areas in the temporal lobe of macaque monkeys supports the visual processing of faces. Most of …

Towards a Better Understanding of Facial Movements: Computational Models for Perception, Characterization, and Neural Production
<p>Facial movements are the primary medium for non-verbal communication and involve a complex orchestration of muscles controlled by the brain. The ability to interpret and produce these movements enables the expression of a wide range of emotions and social cues, all essential for social …
