More Information
Summary:An image processing method that exploits the higher density information contained in the phase component of a DCT transform with respect to the corresponding magnitude component. Methods for image comparison, motion estimation, change detection and edge and highfrequency emphasizing utilizing solely the DCT phase are proposed. L'invention concerne un procédé de traitement d'image utilisant les informations de densité supérieure contenues dans la composante de phase d'une transformation TCD par rapport à la composante d'amplitude correspondante. L'invention concerne des procédés de comparaison d'images, d'estimation de mouvement, de détection de changement et d'accentuation de bord et de haute fréquence utilisant uniquement la phase TCD.
