Dossier – Mineral oil hydrocarbons

Courrieu – dossier HDR II

This paper presents an algorithm that allows for encoding probability density functions associated to samples of points of R. The resulting code is a sequence of points of R whose density function approximates that of the set of data points. However, contrarily to sampled data points, code points associated to two different density functions can be matched, which allows to efficiently compare s...
