Yue Guo · Journal of Shanghai, Maritime University · 2005
An embedded-coding watermarking algorism based on human vision system (HVS) and watermarking energy is presented. This algorism embeds watermark in key coefficients of wavelet domain of images, and it provides the mechanism of embedding the optimal intensity of watermark for users according to the PNSR and visual-masking eigenvalue given by users. The paper also employs and improves. The idea of quantities subsection embedding in the implementation of embedding watermark. Experiments results show that the method offers fine invisibility and robustness in image processing. Its potential application promises well.
