Geometry Issues of Gaze Estimation

چکیده
Video-oculography (VOG) is a non-intrusive method used to estimate gaze. The method is based on a remote camera(s) that provides images of the eyes that are processed by a computer to estimate the point at which the subject is gazing in the area of interest. Normally, infrared (IR) light-emitting diodes (LEDs) are used in the system, as this light is not visible to humans. The objective of the light source is to increase the quality of the image and to produce reflections on the cornea. These reflections can be observed in the acquired images (see Figure 1) and represent useful features for gaze estimation.

A Novel Approach for Driver Eye Gaze Estimation using Epipolar Geometry
The objective of this research is to estimate the gaze point of a driver using epipolar geometry. The system requires two video inputs from internal and external views of a vehicle. We use SIFT image descriptor with L-2 norm distance to find putative correspondences, and then we use RANSAC algorithm to estimate robust fundamental matrix between two views. Once the underlaying scene geometry is ...
متن کاملGeometric Generative Gaze Estimation (GE) for Remote RGB-D Cameras
We propose a head pose invariant gaze estimation model for distant RGB-D cameras. It relies on a geometric understanding of the 3D gaze action and generation of eye images. By introducing a semantic segmentation of the eye region within a generative process, the model (i) avoids the critical feature tracking of geometrical approaches requiring high resolution images; (ii) decouples the person d...
متن کاملCanons and Controversies: The Critical Gaze on Jhumpa Lahiri’s Fiction
The South Asian American diasporic writer, Jhumpa Lahiri has been widely acclaimed by the first-world intellectuals for her truthful representations of diasporic experience. In recent years, however, some scholars have drawn upon Gayatri Spivak’s notion of “Native Informant” to interrogate the controversial canonization of Lahiri in the West, and point instead to her disavowed participation in ...
متن کاملEye Gaze Estimation from a Single Image of One Eye
In this paper, we present a novel approach, called the “one-circle” algorithm, for measuring the eye gaze using a monocular image that zooms in on only one eye of a person. Observing that the iris contour is a circle, we estimate the normal direction of this iris circle, considered as the eye gaze, from its elliptical image. From basic projective geometry, an ellipse can be backprojected into s...
متن کاملResearch Issues in Designing Improved Eye Gaze Based Hci Techniques for Augmentative and Alternative Communication
Augmentative and Alternative communication (AAC) refers to the domain of communicating methods or techniques that provide improved human-human or human-system interaction. AAC techniques enable users with certain communication disabilities to participate in everyday conversations with or without helpers. Eye gaze is a very significant area of human computer interaction (HCI). The gaze estimatio...
