Local Frequency Analysis with Two-Dimensional Wavelet Transform

Résumé : An algorithm for the characterization of local frequencies in two-dimensional signals is described. The algorithm generalizes to the 2D situation a method previously proposed in the 1D context, based on the analysis of the phase of the continuous wavelet transform. It uses families of wavelets generated from a unique one by shifts, dilations and rotations. Résumé: On décrit un algorithme permettant la caractérisation de fré-quences locales dans les signaux bidimensionnels. L'algorithme est la géné-ralisation bidimensionnelle d'une méthode précédemment proposée dans le contexte unidimensionnel, basée sur l'analyse de la phase de la transformée en ondelettes continue. Il utilise une famille d'ondelettes engendréesengendrées`engendréesà partir d'une unique fonction par translations, dilatations et rotations.
