基于视觉特征的图像水印系统的设计与实现

Design and Implementation of Image Watermarking System Based on Visual Features

摘要: 随着互联网的发展，图像和音频这样的数字作品大量出现，而因为数字作品易复制易传播，数字作品侵权问题日益严重。数字水印技术可以非常有效的保护版权。数字水印技术通过分析人类视觉特性和重要领域的视觉掩蔽特性，它可以使用视觉特征敏感纹理图像的对比度和特性来屏蔽人类视觉系统(HVS)。最后，水印信息被自适应地插入到重要区域的域。结果表明，该算法是一种有效的图像水印算法，可以有效地解决水印嵌入过程中水印容量、视觉透明度和鲁棒性之间的平衡问题。

Abstract: With the development of the Internet, digital works such as images and audio have proliferated, the infringement of digital works is becoming increasingly serious. As digital works are easy to be copied and spread, the problem of infringement of digital works is more and more serious. Digital watermarking is a very effective means of copyright protection. Digital watermarking technology can protect copyright effectively. Digital watermarking technology can mask the human visual system (HVS) by using the contrast and characteristics of visual feature-sensitive texture images through analyzing the characteristics of human vision and the visual masking characteristics of important fields. Finally, the watermark information is adaptively included in the DFT domain name of the important domain. The results show that this algorithm is an effective image watermarking algorithm, which can effectively solve the balance between watermark capacity, visual transparency and robustness in the process of watermark embedding.
