Abstract

Une image en couleur de relativement grandes dimensions est insérée dans les données de signal audio sous forme de filigrane. Et pourtant, les données du signal audio incluant le filigrane peuvent être restituées avec une qualité sonore très proche de celle des données de signal audio original. Ces données de signal audio original sont mises en forme de matrice de façon à correspondre au format d'un fichier d'image en couleur avant transformée par ondelettes pendant que le fichier d'image en couleur subit une conversion de format avant la transformation par cosinus discret. Les coefficients des données du signal audio transformé et l'image en couleur reformatée sont combinés avant remise en forme de matrice inverse, puis transformés par ondelettes inverse de façon à générer finalement un signal audio dans lequel un filigrane en image couleur a été inséré.
