- An adaptive image watermarking algorithm is proposed based on block Discrete Cosine Transformation(DCT) and the improved perceptual model of Human Visual system(HVS).At first, the digital watermark is transformed by Arnold, then it is effective to make full use of the improved perceptual model in DCT domain and the feature of the subblock luminance to control the strength of the watermark embedded.However, the method can perfect the fidelity of the host image and the robustness of digital watermark. Simulation results demonstrate that the algorithm of watermarking system make a great balance between transparency and robustness, which has a certain practical value.
