Description: Abstract- H.264/AVC is becoming a popular video codec for
its better compression ratio, lower distortion and applicability
to portable electronic devices. Thus, issues of copyright
protection appropriate for this standard become very
important. In this paper, a new blind SVD (Singular Value
Decomposition) - DCT combined video watermarking scheme
for the ".264 standard is proposed. The proposed method is a
blind watermarking algorithm as the hidden information can be
extracted without the original video and the original singular
values. To reduce visual quality degradation caused by
coefficients modifying, the perceptual model and block selection
mechanism are introduced to control the modification strength.
The performance of the proposed algorithm is evaluated with
respect to imperceptibility, robustness and data payload.
Experimental results reveal that the proposed scheme achieves
enough robustness while preserving the perceptual quality.-Abstract- H.264/AVC is becoming a popular video codec for

Description: 随着现代信息技术的高速发展，人们对信息技术的要求越来越高。对我们所需要的信息的安全性、保密性、版权所有性更加的关注。基于此，数字水印技术就应用而生。数字水印技术就是把一些隐藏的信息嵌 。入到数字信息的载体中，数字水印技术把这些信息从一种形式转换为另一种形式，就类似于把信号从时域转换为频域后再去处理问题。数字水印可分为盲水印和非盲水印， 非盲水印系统在检测或提取水印信息时，需要原始图像而且还会影响到人们的视觉感应；盲水印系统在检测或提取水印过程中，既不需要原始载体图像，也不需要嵌入的水印，因此盲水印系统有着更加广泛的应用。-With the rapid development of modern information technology, the information technology of the increasingly high demand. Security, privacy, copyright on the information we need attention all the more. Based on this, the digital watermarking technology is applied. Digital watermarking technique is to some hidden information block. The carrier into the digital information, the digital watermarking technology the information is converted from one form to another, similar to the signal from the time domain into the frequency domain and then to deal with the problem. Digital watermarking can be divided into blind watermarking and non-blind watermark, non-blind watermarking system in testing or when extracting the watermark information, need the original image but also affect the visual perception of people blind watermarking system in detecting or watermark extraction process, does not need the original carrier image, also do not need to embed the watermark, the watermark the system has a Platform: |
