Abstract :
An image watermarking scheme in a DCT domain is proposed. It is adaptive in that a different strength of watermark is applied to different blocks according to their block classification. For the classification, visual masking (both luminance and texture masking) is taken into account. Consequently, the watermarks thus generated are robust and invisible
