We define, using difference operators, a class of functions on the set of points with integer coordinates which is preserved under the formation of marginal functions.

Interest operators play an important role in computer vision. Depending on the type of the environment some features may prove to be more advantageous than others. Thus detection of interesting features has to be made adaptive such that the best features according to some measure are extracted. We are trying to evolve such feature detectors using genetic programming. In this paper we describe o...

Teams face a wide variety of tasks, have a wide variety of work styles, and may work in geographically distributed locations. While many people believe networked computers will enhance teamwork, research into how this will be accomplished is in its infancy. And... while networks are getting faster and cheaper, they are often overloaded. Computer systems supporting teams must adapt to a wide var...

-This paper discusses the ways in which automation of industrial processes may expand rather than eliminate problems with the human operator. Some comments will be made on methods of alleviating these problems within the "classic' approach of leaving the operator with responsibility for abnormal conditions, and on the potential for continued use of the human operator for on-line decision-making...

The properties of the Volume operator in Loop Quantum Gravity, as constructed by Ashtekar and Lewandowski, are analyzed for the first time at generic vertices of valence greater than four. The present analysis benefits from the general simplified formula for matrix elements of the Volume operator derived in [24], making it feasible to implement it on a computer as a matrix which is then diagona...

We consider abstract operator equations Fu = y, where F is a compact linear operator between Hilbert spaces U and V , which are function spaces on closed, finite dimensional Riemannian manifolds, respectively. This setting is of interest in numerous applications such as Computer Vision and non-destructive evaluation. In this work, we study the approximation of the solution of the ill-posed oper...

Let G = Z4. We construct examples of G-equivariant entire rational maps from non-singular real algebraic G-varieties to Grassmannians with appropriate actions of G. These examples of strongly algebraicZ4 vector bundles facilitate a key step in the verification of Conjecture1.1 in the general cyclic group action case.

Teams of small and micro UAVs currently require at least one operator per vehicle to watch video and plan paths. Each of the operators has a dull and difficult job to constantly monitor the video and coordinate with other operators to ensure the region of interest in covered. This paper presents initial steps towards an approach that would allow a single operator to utilize data from several UA...
