从小波变换后的中、低频子带中选出小波系数嵌入水印
该技术将不可见信息嵌入到数字化媒体中
the information hiding teleology has become a hotspot in the current information science field
Digital watermarking is a main part of information hiding technology
Through embedding the invisible information into digital media
数字水印技术是信息隐藏技术的一个主要分支
达到水印可见性和鲁棒性的最佳折中
论文设计了一种在小波域中、低频部分嵌入水印的算法
and then tracking the use of image by checking the hiding information
