Consider the problem of estimating a signal from noisy samples. The conventional approach (e.g., Shannon-Nyquist sampling) is to sample at many locations in a non-adaptive and more-or-less uniform manner. For example, in a digital camera we collect samples at locations on a square lattice (each sample being a pixel). Under certain scenarios though there is an extra flexibility, and an alternati...

Decision making is a routine cognitive function whose underlying neurobiological mechanisms are presently unclear. In humans, damage to parts of the prefrontal cortex was associated with prolonged deliberation over choices, as well as with impulsive, risky behaviour. Here we suggest a simplified neural circuit, that chooses a given motor action by weighing the efforts and rewards expected from ...

Absfruct-The principle of trinocular stereo is well known in the domain of passive devices and has application in active metrology as well. Trinocular active devices have the advantage of freedom from mechanical scanning and rapid image capture compared with more conventional active designs based on scanning laser stripes. Their eflicient operation relies, however, on a good solution to the cor...

Active three-dimensional vision is concerned with extracting information from the geometry and the texture of the visible surfaces in a scene, reasoning about the data and finally, communicating the results. With the recent technological advances made in electronics, photonics, computer vision and computer graphics, it is now possible to construct reliable, high resolution and accurate three-di...

Sharing and integrating Remote Sensing (RS) and Geographic Information System/Science (GIS) models are critical for developing practical application systems. Facilitating model sharing and model integration is a problem for model publishers and model users, respectively. To address this problem, a framework based on a Web service for sharing and integrating RS and GIS models is proposed in this...
