| 摘 要： | 随着现代社会对信息承载量的需求越来越多,提出了一种基于双通道的三维效果宿主图像的半色调全息水印方法。该方法利用双通道技术将两幅三维效果宿主图像的半色调全息水印图像合成一幅图,接着制作成计算全息图,在重现的时候,一幅计算全息图能够显示出两幅水印图像。制作成的计算全息图可以增加信息传输中的安全性与保密性,双通道技术可以增加传输过程中的信息量,三维效果技术可以在不改变编码效率的情况下增强视觉效果。半色调编码全息水印能更好地提升全息水印的鲁棒性。

| Abstract: | With the increasing demand for information carrying capacity in modern soliety, a halftone holographic watermarking method based on dual channel 3D effect host image is proposed. The method based on dual channel technology combines two 3D host images of holographic watermark halftone into one image. Then, calculating hologram is produced, and a pair of calculating hologram can display two watermark images during reproduction. The resulting calculating hologram can increase the security and confidentiality of information transmission. Double channel technique can increase the amount of information. The process can improve the visual effect meanwhile keeping coding efficiency. The halftone coded holographic watermark can better improve the robustness of the holographic watermark. |
