Real-coded generic algorithm for optimized digital watermarking embedding in time-domain

To reduce the effects of the watermarking embedding on graphic visibility, the optimal watermarking embedding problem using generic algorithm in time-domain is researched in this paper and a real-coded generic algorithm for optimized digital watermarking embedding in time-domain technique is proposed. Through analyzing the corresponding relationship between genotype and phenotype of decision variables, a real-coded algorithm applying position of embedded points as the genotype of the decision variables is proposed. Moreover, this algorithm improves the invisibility and the operating precision of images and reduces the operating complexity shown in simulating experiments.
