Title
(EN) SYSTEMS AND METHODS FOR SYNCHRONIZING A VIDEO SIGNAL WITH AN AUDIO SIGNAL
(FR) SYSTÈMES ET PROCÉDÉS DE SYNCHRONISATION D'UN SIGNAL VIDÉO AVEC UN SIGNAL AUDIO
Abstract
(EN) A system and method for synchronizing a video signal with an audio signal, including: extracting at least one parameter of an audible attribute of the audio signal, the audible attributes including temporal characteristics of the audio signal such as audio intensity, beats, pitch energy, meter, auditory novelty, onset timing and sub sections, and functions applied to any of the attributes in the list; and applying manipulations on the visual signal, wherein parameters of the manipulations are affected by the parameters of the audible attributes. The system and method may further include calculating a probability density function based on the audible attribute, wherein the manipulations are applied based on the probability density function.
(FR) L'invention concerne un système et un procédé de synchronisation d'un signal vidéo avec un signal audio, faisant appel à : l'extraction d'au moins un paramètre d'un attribut audible du signal audio, les attributs audibles comprenant des caractéristiques temporelles du signal audio telles qu'une intensité audio, des battements, une énergie de hauteur, un élément de mesure, une nouveauté auditive, une temporisation de début et des sous-sections, et des fonctions appliquées à l'un quelconque des attributs de la liste ; et l'application de manipulations au signal visuel, des paramètres des manipulations étant affectés par les paramètres des attributs audibles. Le système et le procédé peuvent en outre faire appel à un calcul d'une fonction de densité de probabilité sur la base de l'attribut audible, les manipulations étant appliquées sur la base de la fonction de densité de probabilité.
