Tracking Facial Motion

by Irfan A. Essa, Trevor Darrell, Alex Pentland - In Proceedings of the Workshop on Motion of Nonrigid and Articulated Objects , 1994
"... We describe a computer system that allows real-time tracking of facial expressions. Sparse, fast visual measurements using 2-D templates are used to observe the face of a subject. Rather than track features on the face, the distributed response of a set of templates is used to characterize a given f ..."

and interpret complex facial motions. 1 Introduction The communicative power of the face makes the modeling of facial expressions and the tracking of the expressive articulations of a face an important problem in computer vision and computer graphics. Consequently, several researchers have begun to develop

Differential Processing of Facial Motion

by Tamara L. Watson, Alan Johnston, Harold C. H Hill, Nikolaus Troje
"... Abstract. To investigate viewpoint dependence in dynamic faces an avatar was animated using actors ’ movements. In Experiment 1 subjects were shown a fullface animation. They were then asked to judge which of two rotated moving avatars matched the first. Test view, orientation and the type of motion ..."

of motion were manipulated. In a second experiment subjects were shown two views of the same facial animation and were asked which of the two avatars was the same as the initial animation. Initial views could be rotated to 15 ° and 45 ° or 45 ° and 75 ° while test views were presented at 30 ° or 60°. Learnt

Tracking and Recognizing Rigid and Non-Rigid Facial Motions using Local Parametric Models of Image Motion

by Michael J. Black, Yaser Yacoob - In ICCV , 1995
"... This paper explores the use of local parametrizedmodels of image motion for recovering and recognizing the non-rigid and articulated motion of human faces. Parametric flow models (for example affine) are popular for estimating motion in rigid scenes. We observe that within local regions in space and ..."

and time, such models not only accurately model non-rigid facial motions but also provide a concise description of the motion in terms of a small number of parameters. These parameters are intuitively related to the motion of facial features during facial expressions and we show how expressions

Analysis and Synthesis of Behavioural Specific Facial Motion

by Lisa Nanette Gralewski , 2007
"... This thesis presents work concerning the analysis of behaviour specific facial motion and its automatic synthesis. Psychology research has shown that facial motion provides important cues to the human visual system for recognition of emotion, identity and gender. Similarly, in Computer Vision facial ..."

View Dependence of Complex Versus Simple Facial Motions

by Christian Wallraven, Douglas W. Cunningham, Martin Breidt, Heinrich H. Bülthoff - ACM SIGGRAPH , 2004
"... In this study we investigate the viewpoint dependency of complex facial expressions versus simple facial motions (so-called “action units ” [Ekman and Friesen 1978]). The results not only shed light on the cognitive processes underlying the processing of complex ..."

Event-Related Alpha Suppression in Response to Facial Motion

by Christine Girges, Michael J. Wright, Janine V. Spencer, Justin M. D. O’brien , 2014
"... While biological motion refers to both face and body movements, little is known about the visual perception of facial motion. We therefore examined alpha wave suppression as a reduction in power is thought to reflect visual activity, in addition to attentional reorienting and memory processes. Ninet ..."

Extracting Facial Motion Parameters by Tracking Feature Points

by Takahiro Otsuka, Jun Ohya - In Proceedings of First International Conference on Advanced Multimedia Content Processing , 1998
"... . A method for extracting facial motion parameters is proposed. The method consists of three steps. First, the feature points of the face, selected automatically in the first frame, are tracked in successive frames. Then, the feature points are connected with Delaunay triangulation so that the motio ..."

What the human brain likes about facial motion

by Johannes Schultz, Matthias Brockhaus, Heinrich H. Bülthoff, Karin S. Pilz - Cerebral Cortex , 2013
"... Facial motion carries essential information about other people’s emotions and intentions. Most previous studies have suggested that facial motion is mainly processed in the superior temporal sulcus (STS), but several recent studies have also shown involve-ment of ventral temporal face-sensitive regi ..."

Impaired Perception of Facial Motion in Autism Spectrum Disorder

by Janine Spencer, Christine Girges, Alan Johnston, Harold Hill , 2014
"... Facial motion is a special type of biological motion that transmits cues for socio-emotional communication and enables the discrimination of properties such as gender and identity. We used animated average faces to examine the ability of adults with autism spectrum disorders (ASD) to perceive facial ..."
