We propose a novel formulation for parsing facade images with user-defined shape prior. Contrary to other state-of-the-art methods, we do not explore the procedural space of shapes derived from a grammar. Instead we formulate parsing as a linear binary program which we solve using dual decomposition. The algorithm produces plausible approximations of globally optimal segmentations without gramm...

We re-examine various issues surrounding the definition of twisted quantum field theories on flat noncommutative spaces. We propose an interpretation based on nonlocal commutative field redefinitions which clarifies previously observed properties such as the formal equivalence of Green’s functions in the noncommutative and commutative theories, causality, and the absence of UV/IR mixing. We use...

A phase space mathematical formulation of quantum mechanical processes accompanied by and ontological interpretation is presented in an axiomatic form. The problem of quantum measurement, including that of quantum state filtering, is treated in detail. Unlike standard quantum theory both quantum and classical measuring device can be accommodated by the present approach to solve the quantum meas...

We consider the problem of optimal planning in stochastic domains with metric resource constraints. Our goal is to generate a policy whose expected sum of rewards is maximized for a given initial state. We consider a general formulation motivated by our application domain – planetary exploration – in which the choice of an action at each step may depend on the current resource levels. We adapt ...

States of a quantum mechanical system are represented by rays in a complex Hilbert space. The space of rays has, naturally, the structure of a Kähler manifold. This leads to a geometrical formulation of the postulates of quantum mechanics which, although equivalent to the standard algebraic formulation, has a very different appearance. In particular, states are now represented by points of a sy...

Satellite conjunctions involving “near misses” of space objects are becoming increasingly likely. One approach to risk analysis for them involves the computation collision probability, but this has been regarded as having some counterintuitive properties and its interpretation debated. This paper formulates an satellite conjunction based on a simple statistical model discusses inference miss di...

The spinorial local world-line κ-symmetry of the covariant Brink-Schwarz formulation of the 4-D superparticle is abelian in an off-shell phase-space formulation. The result is shown to generalize to the extended spinorial transformations of the spinning superparticle. ∗ Dept of Physics, University of Tasmania, Hobart Tas 7001 Australia

A recently developed Spatial Operator Algebra approach to modeling and analysis of multibody robotic systems is used to develop O(n) recursive algorithms which compute the Operational Space mass matrix and the Operational Space coriolis/centrifugal and gravity terms of an n{link serial manipulator. These algorithms enable an O(n) recursive implementation of Operational Space Control.
