Les méthodes de filigrane qui emploient des transformations orthogonales sont très robustes face aux modifications non géométriques telles que la compression avec perte, mais il est difficile d'atteindre une robustesse face à la traduction ou au recadrage d'image. Ce rapport décrit une méthode de filigrane qui augmente la robustesse contre les modifications géométriques telles que la traduction et le recadrage d'image en intégrant des données de filigrane dans la composante fréquentielle d'une image et en détectant ces données en considérant la différence de phase des coefficients résultant de la traduction de l'image. Les résultats expérimentaux démontrent la robustesse de cette méthode à la fois contre les changements d’image non géométriques, ainsi que contre la traduction et le recadrage d’images.

Abstract: Watermarking methods that employ orthogonal transformations are very robust against non-geometrical modifications such as lossy compression, but attaining robustness against image translation or cropping is difficult. This report describes a watermarking method that increases robustness against geometrical modifications such as image translation and cropping by embedding watermark data in the frequency component of an image and detecting that data by considering the phase difference of the coefficients that results from translation of the image. Experimental results demonstrate the robustness of this method against both non-geometrical image changes and image translation and cropping.
