In the past people have used very different forms of directions depending on how those directions were acquired. If a person is giving another person directions in a familiar area, he will frequently use landmarks to describe the route [10]. If the person gets the route from a personal navigation system though, it will be displayed on a map and make use of(More)
In this paper, we describe our MirrorMap system, a 2D mobile map system that is augmented with live videos. In most major modern cities, traffic cameras and publicly accessible webcams are in abundance. These cameras provide live coverage of given city and are often positioned such that they have superior views of the scene. As such, it would be beneficial(More)
This paper describes a technique, called V-mirroring, for integrating videos taken from different cameras with different viewpoints of the same scene. The term V-Mirroring stems from the use of virtual mirrors in order to composite videos together. These mirrors are placed in the scene, near to the locations of the cameras. Thereafter, for any given camera,(More)
The visuospatial learning of a map on cellphone displays was examined. The spatial knowledge of human participants was assessed after they had learned the relative positions of London Underground stations on a map via passive, marginally active, or active exploration. Following learning, the participants were required to answer questions in relation to the(More)
While face recognition is a fairly trivial task for humans, much of computer vision research has been dedicated to finding an algorithm to teach a computer how to recognize faces. This paper discusses the robustness of the Turk and Pentland ‘Eigenface’ algorithm [1]. The algorithm consists of two stages, the learning stage, which is done offline, and the(More)
We present Tagger, a game designed to reproduce the social interactions of graffiti lifestyle in a geo-accurate virtual mirror world. Players interact by placing user-generated artwork on photo realistic panoramas of the city of San Francisco. Tagger is unique in the scope and accuracy to which it reproduces an entire city in a virtual environment. We(More)
Three experiments were conducted in developing a low resolution proton nuclear magnetic resonance ((1)H NMR) spectroscopic technique to study matrix mobility in fresh and freeze-thawed gelled yolk. The Carr-Purcell-Meiboom-Gill (CPMG) sequence was used to measure spin-spin relaxation times of proton pools representing major yolk constituents. A component(More)
A study of yolks stored up to 168 d at -20 °C was conducted to determine the gelation behavior and mechanism of freeze-thawed yolk. Methods used were rheology, native and sodium dodecyl sulfate polyacrylamide gel electrophoresis (native- and SDS-PAGE), differential scanning calorimetry (DSC), transmission electron microscopy (TEM), particle size analysis,(More)
In this article, an image integration technique called Virtual Mirroring (VM) is evaluated. VM is a technique that combines multiple 2D views of a 3D scene into a single composite image by overlaying views onto virtual mirrors. Given multiple views of a scene, one view is augmented with the remaining views by placing virtual mirrors on the first view and(More)
