Quantum iterated function systems.
An iterated function system (IFS) is defined by specifying a set of functions in a classical phase space, which act randomly on an initial point. In an analogous way, we define a quantum IFS (QIFS), where functions act randomly with prescribed probabilities in the Hilbert space. In a more general setting, a QIFS consists of completely positive maps acting in the space of density operators. This...
متن کاملIterated Nonlocal Means for Texture Restoration
The recent nonlocal means filter is a very successful technique for denoising textured images. In this paper, we formulate a variational technique that leads to an adaptive version of this filter. In particular, in an iterative manner, the filtering result is employed to redefine the similarity of patches in the next iteration. We further introduce the idea to replace the neighborhood weighting...
متن کاملThe Complexity of Satisfiability in Non-Iterated and Iterated Probabilistic Logics
Let L be some extension of classical propositional logic. The noniterated probabilistic logic over L, is the logic PL that is defined by adding non-nested probabilistic operators in the language of L. For example in PL we can express a statement like “the probability of truthfulness of A is at 0.3” where A is a formula of L. The iterated probabilistic logic over L is the logic PPL, where the pr...
متن کاملIterated Denoising for Image Recovery
In this paper we propose an algorithm for image recovery where completely lost blocks in an image/video-frame are recovered using spatial information surrounding these blocks. Our primary application is on lost regions of pixels containing textures, edges and other image features that are not readily handled by prevalent recovery and error concealment algorithms. The proposed algorithm is based...
متن کاملIterated Integrals in Quantum Field Theory
These notes are based on a series of lectures given to a mixed audience of mathematics and physics students at Villa de Leyva in Colombia. The first half is an introduction to iterated integrals and polylogarithms, with emphasis on the case P\{0, 1,∞}. The second half gives an overview of some recent results connecting them with Feynman diagrams in perturbative quantum field theory.
