摘要
本文基于一类新的正交函数系—V系统,提出了一种在图像中植入数字水印的新算法.该方法利用Fibonacci变换的均匀性质,使得水印信息能够均匀地分散到载体图像中.实验表明该算法能够有效地抵抗一些图像攻击,如裁减和噪音等.
Based on a class of second degree orthogonal function system （V System）, a novel digital watermarking method is proposed. Based on the property of unifcxrmity of the corresponding Fibonacci transformation, the watermarking can be distributed uniformly in the host image. Experiment shows that the algorithm has more advantages than what is suggested in [3]. The algorithm can endure severe attacks such as extreme noise levels, very high loss in its data or data packets.
