Abstract

In this paper, we propose a optimization method of watermarking image based on Cort and DCT. Exploiting human visual system characteristics, our method dynamically chooses the appropriate coefficients of the intermediate frequency and watermarked locations according to different image. Experiments show that the watermarking algorithm performs well in robustness and watermarking imperceptibility.
