HVP-Based Efficient Watermarking Scheme in DCT Domain
Ki‐Hong Park, Yoon-Ho Kim, Heau-Jo Kang · 2007
This paper presents a transform-based watermarking scheme based on human visual system. Human visual parameter (HVP) such as sensitivity of contrast (SoC), texture degree, entropy, and standard deviation are useful to ensure the imperceptivility of watermark image. In this approach, we involved these HVP to select the optimal coefficients region in which watermark will be embedded. Several experiments are performed to demonstrate the effectiveness and appropriateness of the proposed scheme. According to experimental results, SoC parameter is superior in smooth image. Meanwhile, statistical characteristics provide good results in rough image. It also suggest that it is more robust and efficient than other state-of the-art algorithm from the literature in terms of the selected spatial-domain watermarking schemes.
