Description: 一种基于视觉模型的DCT数字水印算法
提出了一种水印系统与人眼视觉模型相结合的离散余弦变换数字水印算法。该算法利用了人眼视觉模型
(Hvs)来选取水印嵌入区域，使其既能够保证水印信息的鲁棒性又能够满足其不可见性。利用基于能量关系的算法进
行水印嵌入。最后进行了仿真实验，嵌入水印的图像中很难发现水印的痕迹，具有较高的清晰度。-based on the visual model DCT digital watermarking algorithm presents a watermarking system and the human visual model Guitar with the discrete cosine transform digital watermarking algorithm. The algorithm uses the human visual model (Hvs) to select embedding region, it is to ensure watermark robustness is not able to meet its visibility. Based on the energy use of the embedded watermark algorithm. Finally, the simulation experiments, the embedded watermark image watermark is difficult to find traces of high clarity.
