Zhao Xiao-ying · Science Technology and Engineering · 2011
A watermarking wavelet algorithm based on zerotree structure is proposed.It is carried on in wavelet domain by applying Haar function.And then,basing on the wavelet coefficients,zerotree is selected appropriately by using genetic algorithm to implement the embedding of watermark,which meanwhile guarantees the characteristics of watermark by controlling the number of iteration and the embedding strength.The simulation results indicate that the image watermarking obtained by the proposed algorithm has perfect invisibility and is robust to some common attacks at the same time.
