摘要
提出了一种基于DWT和DCT的自适应图像水印算法.该算法以DWT和DCT变换为基础,自适应选择水印嵌入位置,并且根据HVS亮度掩蔽模型对水印嵌入强度自适应调节.实验证明,本文算法对JPEG压缩、噪声等常规信号处理操作都具有相当好的鲁棒性.
An adaptive image digital watermarking algorithm based on DCT and DWT is presented. By utilizing DCT, DWT and the visual masking of HVS, the watermark can he embedded adaptively into some proper location of the original image. Experimental results show that the presented watermarking scheme is transparent and robust against various usual signal processing such as JPEG compression and noise adding, etc.
