Abstract

Pour insérer des informations comprenant un nombre prédéterminé de symboles, dans une séquence d'images d'au moins une image comportant un nombre prédéterminé de lignes rassemblant chacune un nombre prédéterminé de pixels, ce procédé consiste à : générer un ensemble de fonctions présentant un spectre en forme de peigne s'intercalant dans le spectre de la séquence d'image, et comprenant une fonction respective pour chaque symbole des informations à insérer ; déphaser chaque fonction de l'ensemble de fonctions par une valeur représentative d'un symbole respectif des informations à insérer ; superposer les fonctions déphasées ; et combiner les pixels de la séquence d'images au résultat obtenu par la superposition des fonctions déphasées.
