Passive gaze estimation is usually performed by locating the pupils, and the inner and outer eye corners in the image of the driver’s head. Of these feature points, the eye corners are just as important, and perhaps harder to detect, than the pupils. The eye corners are usually found using local feature detectors and trackers. In this paper, we describe a passive driver gaze tracking system whi...

A spherical n-gon is a bordered surface homeomorphic to a closed disk, with n distinguished boundary points called corners, equipped with a Riemannian metric of constant curvature 1, except at the corners, and such that the boundary arcs between the corners are geodesic. We discuss the problem of classification of these polygons and enumerate them in the case that two angles at the corners are ...

Monocular gaze estimation is usually performed by locating the pupils, and the inner and outer eye corners in the image of the driver’s head. Of these feature points, the eye corners are just as important, and perhaps harder to detect, than the pupils. The eye corners are usually found using local feature detectors and trackers. In this paper, we describe a monocular driver gaze tracking system...

Corners and curves are important image features in many vision-based applications. Corners are usually more stable and easier to match than curves,while curves contain richer information of scene structure. In previously work, corners are often used to recover the epipolar geometry between two views, which is then used in curve matching to reduce the search space. However, information of the sc...

This paper is an extension of our previous paper to improve the capability of detecting corners. We proposed a method of boundary smoothing for curvature estimation using a constrained regularization technique in the previous paper. We propose another approach to boundary smoothing for curvature estimation in this paper to improve the capability of detecting corners. The method is based on a mi...

Abstract We discuss some bulk-surface gapped Hamiltonians on a lattice with corners and propose periodic table for topological invariants related to corner states aimed at studies of higher-order insulators. Our is based four things: (1) the definition invariants, (2) proof their relation states, (3) computations K -groups (4) construction explicit examples.

An elementary kinetic model is established to represent the coupled behavior of (electro)-chemistry, transport and degradation processes in the porous Ni/YSZ anode of solid oxide fuel cells (SOFC). The model is applied to support the development and evaluation of solid carbon formation mechanisms at Ni/YSZ anodes. The simulations of cells operated on partially reformed hydrocarbons show that pe...

Statistical analysis and optimization is critical for robust nanoscale circuit design. To accurately perform such analysis, primary process variation sources must be identified and their distributions must be well characterized. We present a rigorous method to extract process variations from in-situ IV measurements. Transistor statistics are collected from a test chip fabricated in a 65nm SOI p...

Traditionally, courts interpreting written contracts focused primarily on the contract's language. Consideration of factors beyond the "four corners" of the document was discouraged. Modern courts construing standard form insurance contracts have deviated from this course and begun aiding the insured against the insurer. One of the methods used to tilt insurance disputes in favor of the insured...
