- W2394160929 abstract "A new method of embedding a binary digital watermark into a discrete wavelet transformed image combining neural network is proposed.To get better imperceptibility and robustness,and to improve practicability,a digital watermark is embedded in wavelet domain with the new neural network theory in the proposed algorithm innovatively.The approximate part,which may be required from discrete wavelet transform of the original image,is taken as embedding location.Then the model is established and trained using neural network in pixels and their vicinities which are selected randomly from the approximate part.After that,watermark information is embedded by adjusting the value of pixels.Binary digital watermark is pre-treated by Arnold for encryption.The experiment results show that the proposed method has very strong ability of sustaining geometry attack and common image processing operations and has good imperceptibility.Its robustness is superior to other embedding algorithms in wavelet domain.It possesses very good reference value for the realization of digital watermark." @default.
