摘要
以图像反色、图像置乱、离散小波变换和人眼视觉特性为基础,提出了一种新的采用灰度图像作为水印的自适应嵌入方案。实验结果表明,该算法不仅具有较好的透明性,而且对缩放、剪切、JPEG或JPEG2000压缩等图像退化处理或攻击均具有较强的鲁棒性。
The paper presents a scheme of embedding gray-scale image watermark based on image color inversing,image disordering,discrete wavelet transform(DWT) and human visual system(HVS).Experimental results prove that the method is invisible and robust enough against some image degradation processes such as resizing,cropping,JPEG or JPEG2000 compression.
