A novel technique for robust image watermarking in the DCT domain

In this paper, we present a novel algorithm for embedding a watermark into a still host image in the DCT domain. Unlike the traditional techniques, we embed a binary image as a watermark into the dc components of the DCT coefficients of 8/spl times/8 blocks. In the proposed algorithm, we incorporate...
