High-precision camera distortion measurements with a "calibration harp"
Zhongwei Tang, Rafael Grompone von Gioi, Pascal Monasse +1
This paper addresses the high precision measurement of the distortion of a digital camera from photographs. Traditionally, this distortion is measured from photographs of a flat pa…
Generating tuples of integers modulo the action of a permutation group and applications
Nicolas Borie
Originally motivated by algebraic invariant theory, we present an algorithm to enumerate integer vectors modulo the action of a permutation group. This problem generalizes the gene…
Semantic Polarity of Adjectival Predicates in Online Reviews
Ae-Lim Ahn, Éric Laporte, Jee-Sun Nam
Web users produce more and more documents expressing opinions. Because these have become important resources for customers and manufacturers, many have focused on them. Opinions ar…
On multidimensional generalized Cramér-Rao inequalities, uncertainty relations and characterizations of generalized -Gaussian distributions
J. -F. Bercher
In the present work, we show how the generalized Cramér-Rao inequality for the estimation of a parameter, presented in a recent paper, can be extended to the mutidimensional case w…
An Achievable Rate Region for the Broadcast Wiretap Channel with Asymmetric Side Information
Maël Le Treust, Abdellatif Zaidi, Samson Lasaulce
The communication scenario under consideration in this paper corresponds to a multiuser channel with side information and consists of a broadcast channel with two legitimate receiv…
Transforming Monitoring Structures with Resilient Encoders. Application to Repeated Games
Maël Le Treust, Samson Lasaulce
An important feature of a dynamic game is its monitoring structure namely, what the players effectively see from the played actions. We consider games with arbitrary monitoring str…
