摘要
文章提出了一种基于小波变换的、可依据人类视觉系统特性自适应调节嵌入水印位置和强度的数字图像水印嵌入方案。该方案较好地兼顾了对图像水印的不可见性要求和鲁棒性要求。
A scheme of embedding digital image watermark based on wavelet transformation is presented in this paper,which can adaptively adjust the position and intensity of embedded watermark according to the characteristic of human vision system.The scheme meets properly the requirement of invisibleness and robustness for watermark.
