In this paper a face recognition system that is based on illumination subspaces is presented. In this system, first, the dominant illumination directions are learned using a clustering algorithm. Three main illumination directions are observed: Ones that have frontal illumination, illumination from left and right sides. After determining the dominant illumination direction classes, the face spa...

This paper proposes an integrated approach to realtime detection, tracking and direction recognition of human faces, which is intended to be used as an human-robot interaction interface for the intelligent wheelchair. Adaboost face detection is applied inside the comparatively small window which is slightly bigger than the Camshift tracking window, so that the face precise position, size and fr...

Experiments suggesting that a change in eye gaze creates a reflexive attention shift tend to confound motion direction and terminal eye direction. However, motion and the onset of motion are known to capture attention. Current thinking about social cognition in autism suggests that there might be a deficit in responding to social (eye gaze) cues but not non-social (motion direction) cues, makin...

nowadays the surface texturing has been widely recognized as a usable capability to improve the tribological systems. in this paper, ultrasonic assisted turning (uat) isperformed to create the micro textures on the flat faces. micro surface texturing ismade on the al7075-t6 by the uat in the face turning process. then, the influences of cutting speed feed, vibration direction and vibration ampl...

Humans are remarkably adept at interpreting the gaze direction of other individuals in their surroundings. This skill is at the core of the ability to engage in joint visual attention, which is essential for establishing social interactions. How accurate are humans in determining the gaze direction of others in lifelike scenes, when they can move their heads and eyes freely, and what are the so...

This paper seeks to bring together two previously separate research traditions: research on spatial orienting within the visual cueing paradigm and research into social cognition, addressing our tendency to attend in the direction that another person looks. Cueing methodologies from mainstream attention research were adapted to test the automaticity of orienting in the direction of seen gaze. T...
