Adaptive Robust Reversible Watermarking Scheme

摘要

Digital watermarking technology in the field of information hiding technology has become an important means to protect copyright in network transmission. Robust reversible digital watermarking has been studied for many years as a more adaptive technique for network lossy transmission environment. However, the algorithms proposed by the scholars have not done a good job in balancing the embedded distortion and robustness of the human eye. In this paper, an adaptive robust reversible digital watermarking technique is proposed, which distinguishes the texture complex region and the texture smoothing region by the method of complexity prediction, and selects different parameters to realize the function of embedding more bits in the complex texture region and embedding less bits in the smooth region. In this paper, the algorithm has a high robustness to better resist JPEG compression while there is less distortion of human eye observation. Experimental results show that the proposed scheme has better robustness and higher subjective quality than previous schemes.
