Research on Robust and Invisibility of Digital Watermarking Algorithm
Weihua Hu · 2012
Research digital image watermarking algorithm for copyright protection.The paper proposed a new watermarking algorithm based on the neighborhood mean of watermarking algorithm.First Contourlet domain transformation of digital image was carried out to decompose the image,which can increes enhance the robustness of the embedded watermarking.The Arnold transform and encryption were done with the wartermarking image.According to the neighborhood mean quantitative algorithm,the important areas were selected to enbed watermark,which ensures the invisibility of the watermarking and realizes the effective embedded watermarking at last.Experiments show that the method can give consideration to the digital watermarking against the attack,and satisfactory results were obtained.
