摘要
提出了一种基于小波分析的数字水印嵌入检测算法 ,水印的检测不需要原始图像 ,选择中频带嵌入水印信息 ,以保证其隐蔽性和鲁棒性 ,实验表明 。
An embedding and detecting algorithm for digit al watermarking based on wavelet analysis is proposed,and the original image is no t required for detecting the watermark.The watermarking is embedded into the par ts of medium frequency coefficients to guarantee its invisibility and robustness .The experimental results show that the method is feasible and the embedded wate rmarks with the proposed algorithm are invisible and robust enough against the c ommonly used image processing.
