摘要:
伴随着网络技术和多媒体技术的飞速发展,如何保护多媒体信息的安全成为国际上研究的热门课题。数字娈粤技术是保护版权和认证来源及完整性的新型技术,提出了一种基于人类视觉特性HVS和DWT的静态图像数字水粤手法,借鉴了人类视觉特性HVS算法的思想,并做了一些改进。实验表明该算法稳健性较好,有一定的抗裁剪、噪声、压缩和
Abstract:
With the rapid development of the network and the multimedia technical , how protects the security of the multimedia informations becomes the popular topic on internationally studies. The digital watermark technology is anew technology for protecting the copyfight,the authentication origin and integrity. Proposes one kind of gradation image digital watermark algorithm based on human visual system(HVS) and digital wavelet transformation(DWT), has profited from the HVS algorithm thought, and has made some improvements. The experiment indicated this algorithm robustness is good, to cuts out, the noise, the compression, the modification are strong, and the algorithm order of complexity is low, the usability is strong
