Given a game in extensive form and a player p in the game, we want to find a small set of parameters describing a set M of mixed strategies with the property that every mixed strategy for p has an equivalent mixed strategy in M. In the case that the player has perfect recall, behavioral strategies describe such a set. [2] For computational purposes, it is more useful to work with corresponding ...

A number of methods have been proposed in the literature for estimating scenestructure and ego-motion from a sequence of images using dynamical models. Although all methods may be derived from a "natural" dynamical model within a unified framework, from an engineering perspective there are a number of trade-offs that lead to different strategies depending upon the specific applications and the ...

[1] Rising surface air temperatures in response to anthropogenic forcing are intensifying the global hydrologic cycle. Some of the more dramatic signs of climate change are increasing precipitation, evaporation, and freshwater discharge in continental river basins draining to high-latitude oceans. At regional scales, however, an acceleration of the hydrologic cycle is not always detected. In co...

Typical Structure-from-Motion systems spend major computational effort on geometric verification. Geometric verification recovers the epipolar geometry of two views for a moving camera by estimating a fundamental or essential matrix. The essential matrix describes the relative geometry for two views up to an unknown scale. Two-view triangulation or multi-model estimation approaches can reveal t...

Algebraic Reconstruction Technique (ART) is most accurate method for image reconstruction. In present paper the accuracy of ART is shown with parallel projections, in all only 16 projections with about 60 iterations are used to obtain reconstruction. Reference R.

The ability to automate forced landings in an emergency such as engine failure is an essential ability to improve the safety of Unmanned Aerial Vehicles operating in General Aviation airspace. By using active vision to detect safe landing zones below the aircraft, the reliability and safety of such systems is vastly improved by gathering up-to-the-minute information about the ground environment...

This paper investigates the use of computational intelligence for adaptive lesson generation in a distance learning environment. A method for adaptive pedagogical hypermedia document generation is proposed and implemented in a prototype called KnowledgeClass. This method is based on specialized connectionist architecture. The domain model is represented in a connectionist-based system which pro...

Parameterized Appearance Models (PAMs) such as Active Appearance Models (AAMs) or Morphable Models (MMs) are a popular tool to model the shape and appearance of faces in images. Although extensively used, PAMs have some limitations to decouple out-of-plane pose, expression and identity changes. For instance, standard AAMs use a unique basis to model pose, identity and expression changes. On the...

An ensemble of simulations of the climate of the past millennium conducted with a three-dimensional climate model of intermediate complexity are constrained to follow temperature histories obtained from a recent compilation of well-calibrated surface temperature proxies using a simple data assimilation technique. Those simulations provide a reconstruction of the climate of the Arctic that is co...
