Qing Xie, Jianquan Xie, Yunhua Xiao · 2010
Block size, embedding strength, treatment and various attacks have great influence on the imperceptibility and robustness of watermarking in image digital watermarking algorithm. Based on theoretical analysis and experiment, by means of testing and analyzing the influence of watermarking performance from watermarking capacity, block size, embedding strength, conventional treatment and various attacks, this paper relates the parameter selection and watermarking performance of this kind of algorithm. This paper can provide reference for keeping a better balance among the imperceptibility, robustness and watermarking capacity.
