摘要
提出了一种新的利用独立成分分析提取数字水印的方法,把原始图像和数字水印图像在空间域直接混叠,得到两个嵌入水印的图像.通过对混合矩阵的控制实现水印的不可见性.把混合后的图像作为盲源进行分离,在整个提取过程中不需要原始图像和混合矩阵信息.仿真实验表明该方案很好的实现了水印的不可见性和鲁棒性的统一.
The paper proposes a new method of extracting digital watermarking from using independent component analysis. There are two images which are embedded watermarking by mixing the original image and digital watermarking image in the space domain. The watermarking image is invisible under the control of the mixed matrix. Guaranteed high quality images with embedded watermarking. The mixed images are separated as blind source without needing any information of the original images and mixed matrix in the entire extraction process. The simulation experiments indicate that the project achieved a good unification of the robustness and invisibility of the watermarking.
