Description: 基于J PEG2000的数字水印蒋勇(西南科技大学计算机科学与技术学院四川绵阳621010)【摘 要】:网络技术的发展为数字作品的传播提供了方便,同时也引发了对数字作品的盗版现象,如何保护数字作品的版权日益受到关注:JPEG2000作为ISO推荐的新一代静止图像压缩标准,由于其感兴趣区域编码,渐进传输等优越性能,有着广阔的应用前景。本文旨在研究保护JPEG2000图像作品版权的数字水印方案。-based digital watermarking Jiang Yong (Southwest University of Science and Technology Computer Science and Technology Institute in Sichuan Mianyang 621010) Abstract : the development of network technology for the transmission of digital works to provide a convenient, also triggered the right of pirated digital works, how to protect the copyright of digital works have been a growing concern : ISO JPEG2000 as recommended by the new generation of still image compression standard, because of its interest in regional coding, progressive transmission, and other advantages can be as broad application prospects. This paper is to study the protection of JPEG2000 images copyright of digital watermarking programs.

Description: 一种基于视觉模型的DCT数字水印算法 提出了一种水印系统与人眼视觉模型相结合的离散余弦变换数字水印算法。该算法利用了人眼视觉模型 (Hvs)来选取水印嵌入区域,使其既能够保证水印信息的鲁棒性又能够满足其不可见性。利用基于能量关系的算法进 行水印嵌入。最后进行了仿真实验,嵌入水印的图像中很难发现水印的痕迹,具有较高的清晰度。-based on the visual model DCT digital watermarking algorithm presents a watermarking system and the human visual model Guitar with the discrete cosine transform digital watermarking algorithm. The algorithm uses the human visual model (Hvs) to select embedding region, it is to ensure watermark robustness is not able to meet its visibility. Based on the energy use of the embedded watermark algorithm. Finally, the simulation experiments, the embedded watermark image watermark is difficult to find traces of high clarity.

Description: 数字水印技术是指用信号处理的方法在数字化的多媒体数据中嵌入隐蔽的标记,这种标记通常是不可见的,只有通过专用的检测器或阅读器才能提取。数字水印在信息隐藏及图象隐藏方面有着极为广泛的应用。-Digital watermarking technology is that by using the method of signal processing in the digital multimedia data embedded hidden tag, this tag is not usually visible only through a dedicated detector or reader can be extracted. Digital Watermarking and Information Hiding in the hidden image has a very wide range of applications.
