Abstract Face views are particularly important in person-to-person communication. Differenes between the camera location and face orientation can result undesirable facial appearances of participants during video conferencing. This phenomenon is noticeable when using devices where front-facing placed unconventional locations such as below display or within keyboard. In this paper, we take a str...

In this paper, we analyze multiple view geometry under projections from 4D space to 3D space and show that it can represent multiple view geometry under the projection of space with time. In particular, we show that multifocal tensors defined under space-time projections can be computed from non-rigid object motions viewed from multiple cameras with arbitrary translational motions. We also show...

Mathematicians have always struggled with the difficulty of describing to nonmathematicians what they do. This difficulty is said to account for all sorts of ills, such as meager federal funding for mathematics research, low student interest in mathematics, and lack of appreciation for mathematics as a force in human culture. The easiest way to deal with the difficulty is to describe applicatio...

• Consists of descriptions of: – components, connectors, rationale/constraints, ... • Shows high-level structure – Composition and decomposition, horizontal layers and vertical slices • Reflects major design decisions – Rationale for why one approach taken, what impact it has • Promotes shared mental model among developers and other stakeholders – Shows how functional and non-functional require...

Despite significant advances in improving the gaze estimation accuracy under controlled conditions, the tracking robustness under real-world conditions, such as large head pose and movements, use of eye glasses, illumination and eye type variations, remains a major challenge in eye tracking. In this paper, we revisit this challenge and introduce a real-time multi-camera eye tracking framework t...

Pulsar spindown forms a reliable yet enigmatic prototype for the energy loss processes in many astrophysical objects including accretion disks and back holes. In this paper we review the physics of pulsar magnetospheres, concentrating on recent developmen ts in force-free modeling of the magnetospheric structure. In particular, we discuss a new method for solving the equations of time-dependent...
