提出一种新颖的基于HVS (Human Visual System) 和DCT (Discrete Cosine Transform)的数字水印算法。为保证视觉透明性和鲁棒性, 通过将二值水印图像映射为标准正态分布的伪

随机实数序列, 并利用HVS 的特性, 将水印嵌入宿主图像中频部分。-Propose a novel digital watermarking algorithm based on the HVS (Human Visual System) and DCT (Discrete Cosine Transform). To ensure that the visual transparency and robustness, the binary watermark image map for the standard normal pseudo-random sequence of real numbers, and take advantage of the characteristics of the HVS, the watermark is embedded in the IF portion of the host image.
