....strength assuming that the image spectra have isotropic character. This assumption leads to some visible artifacts in images specially in the flat regions, because of anisotropic properties of image spectra. A similar method using blocks in DCT (discrete cosine transform) domain was proposed in [4]. In the context of image compression using perceptually based quantizers, this concept was further developed in [5] to a content adaptive scheme, where the watermark is adjusted for each DCT block. However, as the original image is required to extract the watermark, the practical applications of ....
