一种基于DCT数字水印新算法 该算法利用了新的算法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-A new algorithm based on DCT digital watermarking algorithm uses a new algorithm to select the watermark embedding area, making it both to ensure the robustness of the watermark information and be able to meet its invisibility. Based on the relationship between energy use watermark embedding algorithm. Finally, the simulation experiments, the watermarked image is difficult to find traces of the watermark, has a high clarity
