While production studies of allophonic variation are now commonplace, we still do not have a clear understanding of how and if native speakers perceive subphonemic differences. This project experimentally investigates the perception of the variable process of intervocalic /s/ voicing in Spanish and shows that, while distinct from categorical perception, allophonic perception is displayed by lis...

In this chapter, we report an investigation the influence of the saliency of another person’s direction of gaze on an observer’s eye movements through real-world scenes. Participants’ eye movements were recorded while they viewed a sequence of scene photographs that told a story. A subset of the scenes contained an actor. The actor’s face was highly likely to be fixated, and when it was, the ob...

in this paper, a novel patch geodesic derivative pattern (pgdp) describing the texture map of a face through its shape data is proposed. geodesic adjusted textures are encoded into derivative patterns for similarity measurement between two 3d images with different pose and expression variations. an extensive experimental investigation is conducted using the publicly available bosphorus and bu-3...

a fundamental assumption in prosthetic dentistry is that the axis-orbital plane will usually be parallel to the horizontal reference plane. most articulator systems have incorporated this concept into their designs and use orbitale as the anterior reference point for transferring the vertical position of the maxilla to the articulator. clinical observations of cantonese patients suggest that in...

objective: deficits in the processing of facial emotions have been reported extensively in patients with schizophrenia. to explore whether restricted attention is the cause of impaired emotion processing in these patients, we examined visual attention through tracking eye movements in response to emotional and neutral face stimuli in a group of patients with schizophrenia and healthy individual...

This work presents a comparison among different focus measures used in the literature for autofocusing in a non previously explored application of face detection. This application has different characteristics to those where traditionally autofocus methods have been applied like microscopy or depth from focus. The aim of the work is to nd if the best focus measures in traditional applications o...

This paper aims at generating a new face based on the human like description using a new concept. The FASY (FAce SYnthesis) System is a Face Database Retrieval and new Face generation System that is under development. One of its main features is the generation of the requested face when it is not found in the existing database, which allows a continuous growing of the database also.
