【 摘 要 】

One of the ways for implicit protection of rightful copyright information deals with application of visible watermark embedded in the host image. In this paper, we study behaviour of the proposed function, which makes the embedding of visible watermark smoother compared to the well-known sigmoid function, linear function, and Zernike moments. The Hadamard transform allows us to reduce the computational resources for watermarking processes. The proposed technique is especially useful in fragile watermarking as the additional level for protection.
