Translation invariant transformations of discrete random sets

Proceedings SIBGRAPI'98. International Symposium on Computer Graphics, Image Processing, and Vision (Cat. No.98EX237), 2002
Random modeling is an important technique for solving hard problems in coding, quantitative description and restoration of images. In the sixties. Matheron introduced the theory of Random Closed Sets (RACS), that permits the creation of models by morphological transformations of primitive processes.

Translating Discrete-Time Simulink to Lustre

2003
We present a method of translating discrete-time Simulink models to Lustre programs. Our method consists of three steps: type inference, clock inference and hierarchical bottom-up translation. In the process, we formalise typing and timing mechanisms of Simulink. The method has been implemented in a prototype tool called S2L.

Discrete translates in Lp (R)

2015
A set Λ is called p-spectral if there is a function g∈Lp(R) such that all Λ-translates {g(t−λ),λ∈Λ} span Lp(R). We prove that exponentially small non-zero pertubations of the integers are p-spectral for all p>1.

Translation of Timed Promela to Timed Automata with Discrete Data

Fundamenta Informaticae, 2008
The aim of the work is twofold. In order to face the problem of modeling time constraints in Promela, a timed extension of the language is presented. Next, timed Promela is translated to timed automata with discrete data, that is timed automata extended with integer variables.

Translations of the Discrete Bose-Einstein Operators

Journal of Mathematical Physics, 1966
The effects on a certain family of representations of the commutation relations of the operator-translations ak → ak + ck, ak* → ak* + ck*, are investigated. Here ak and ak* are the annihilation and creation operators of the representations, the ck are complex numbers (scalar operators), and the representations considered are the discrete ...

Translation of Intermediate Language to Timed Automata with Discrete Data

Fundamenta Informaticae, 2008
The aim of this work is to describe the translation from Intermediate Language, one of the input formalisms of the model checking platform VerICS, to timed automata with discrete data and to compare it with the translation to classical timed automata. The paper presents syntax and semantics of both formalisms, the translation rules as well as a simple ...

Random translation of discrete order statistics

Statistics, 2013
We investigate the existence and uniqueness of a discrete parent distribution supported on the integers whose order statistics are related by a random translation. We also provide some examples using the constructive method that we propose.

Uniform discreteness and Heisenberg translations

Mathematische Zeitschrift, 1997
Let \(G\) be a discrete subgroup of \({\mathbf P} {\mathbf U} (n,1)\) containing a Heisenberg translation \(g\). The purpose of this paper is to show that any element of \(G\) not sharing a fixed point with \(g\) has an isometric sphere whose radius is bounded above by a function of the translation length of \(g\) at its centre.

PERFECT-TRANSLATION-INVARIANT CUSTOMIZABLE COMPLEX DISCRETE WAVELET TRANSFORM

International Journal of Wavelets, Multiresolution and Information Processing, 2013
The theorems, giving the condition of perfect translation invariance for discrete wavelet transforms, have already been proven. Based on these theorems, the dual-tree complex discrete wavelet transform, the 2-dimensional discrete wavelet transform, the complex wavelet packet transform, the variable-density complex discrete wavelet transform and the ...

Translation invariant complex discrete wavelet transforms

2008 International Conference on Wavelet Analysis and Pattern Recognition, 2008
The CDWT was first proposed by Kingsbury as a tool for motion estimation in 1998. It was effective at solving the problem of poor translation invariance in the traditional DWT and has been applied in various fields. Thus, its practical use occurred early on, and its rationality was not theoretically interpreted.
