图像多水印共存的算法

Algorithm of Embedding Multi-watermarking in Digital Image

在多数实际应用中需要多水印,本文提出在灰度图像低频多次嵌入水印的方案,讨论了重复嵌入对图像质量的影响,实验分析结果证实了多水印设计方案的不可见性及其有效性.

Multi-watermark is often required in many applications.A kind of multi-watermarking schemes was proposed,embedding low frequency images into gray-level-image.These watermarks and their impact on the image quality were discussed.The method has been proved invisibility and effective by theoretic analysis.
