An Improved Robust Digital Watermarking Algorithm Base on Wavelet Decomposition

Based on Deepa Kundur’s paper1,in this paper we present an improved version with stronger robustness.Instead of random picking,we select embedding position according with HVS characteristic,and by mathematicaI deduction.Specific conditions are given to make sure the algorithm works well when the quantified distance iS tiny or even 0.Which iS impossible for the original algorithms.In this way,both robustness and imperceptibility are guaranteed.Experiment results show that proposed algorithm greatly enhanced the abUity to against various attacks,especially cropping,as well as offering superior advantages over Deepa’s algorithms.
