Une nouvelle méthode d'intégration de données pour des images de haute qualité, par exemple une image avec un rapport signal/bruit maximal supérieur à 60 [dB], est proposée dans cet article. La méthode proposée génère avec précision une image filigranée de la qualité souhaitée et de haute qualité pour toutes les images. Pour ce faire, ce procédé considère la longueur de mot finie d'une valeur de luminance de pixels, c'est-à-dire à la fois les erreurs de quantification et la limitation de plage de luminance. La méthode proposée intègre une séquence de filigrane, modulée par le mécanisme d'un schéma à spectre étalé, dans les valeurs DC d'une image dans le domaine spatial. En utilisant la technologie à spectre étalé et en intégrant un filigrane dans les valeurs DC, cette méthode garantit une qualité d'image élevée et, simultanément, offre une tolérance JPEG adéquate.

Abstract: A novel data embedding method for high-quality images, e.g., an image with a peak signal-to-noise ratio of better than 60 [dB] is proposed in this paper. The proposed method precisely generates a watermarked image of the desired and high quality for any images. To do this, this method considers the finite word-length of a luminance value of pixels, i.e., both quantization errors and the range limitation of luminance. The proposed method embeds a watermark sequence, modulated by the mechanism of a spread spectrum scheme, into the dc values of an image in the spatial domain. By employing spread spectrum technology as well as embedding a watermark into the dc values, this method guarantees the high image quality and, simultaneously, provides adequate JPEG tolerance.
