内容記述 | Digital watermarking schemes need to have robustness to attacks, such as the processes of noise reduction and JPEG compression etc. From the viewpoint of the robustness, we paid attention to the low frequency areas LL_2 and LL_3 of wavelet transform in spite of the weakness of image quality degradation being easily visible. We propose a atermarking scheme based on the wavelet transform which uses an adaptive quantization methd for improvement of the image quality, and moreover, a determination method by majority occurrence for making the system robust to attacks. Simulation results show that the proposed methd have a good picture qualitv with robustness for JPEG attacks. | |||||
