Characterizing Musical Signals with Wigner-Ville Interferences

This paper presents a new characterization of musical signals which may lead to better understanding about how such signals are perceived. We first consider some signal analysis methods which facilitate measures of perceived qualities of music. More precisely, we consider a particular representation of signal energy on which to base a quantitative measure of sensory dissonance. After defining s...

VILLE – Multilanguage Tool for Teaching Novice Programming

Visualization tools have proven to be useful for enhancing novice programming learning. However, those tools are typically tide to a certain programming language and focus to low level aspect of programming such as changing value of variables during code execution. In this paper, we present a new program visualization tool which provides a language independency view of learning programming and ...

Von Neumann, ville, and the minimax Theorem

Von Neumann proved the minimax theorem (existence of a saddle-point solution to 2 person, zero sum games) in 1928. While his second article on the minimax theorem, stating the proof, has long been translated from German, his first announcement of his result (communicated in French to the Academy of Sciences in Paris by Borel, who had posed the problem settled by Von Neumann’s proof) is translat...

Texture discrimination using the Wigner-Ville distribution

In this paper we present a very effective method for texture segmentation and analysis using a local spectral method. The idea is to use a modular pattern detection in textured images based on the use of a Pseudo-Wigner Distribution (PWD) followed by a decorrelation procedure that consists of a principal component analyzer (for texture segmentation). The goal is to combine the advantages of a h...
