Özet
This paper presents a method for robust watermarking of digital images in wavelet domain. A new HVS model which uses local entropy in addition to conventional masking characteristics of the human visual system such as frequency, luminance and contrast masking has been utilized to increase the robustness of the scheme. Experimental results demonstrate the superiority of the proposed method over the similar method in terms of robustness and transparency.
