A regional perceptual classifier is employed to assign a noise sensitivity index to each region. The watermark is inserted in the original
10、 image according to this index by using block DCT. The detection of the watermark is designed to achieve a desired false alarm probability. Digital watermarking has been proposed as a solution to the problem of copyright protection of multimedia data in a networked environment. It makes possible to
11、tightly associate to a digital document a code allowing the identification of the data creator, owner, authorized consumer, and so on. In this paper a new watermarking algorithm for digital images is presented: the method, which operates in the frequency domain, embeds a pseudo-random sequence of re
12、al numbers in a selected set of DCT coefficients. After embedding, the watermark is adapted to the image by exploiting the masking characteristics of the human visual system, thus ensuring the watermark invisibility. By exploiting the statistical properties of the embedded sequence, the mark can be
13、reliably extracted without resorting to the original uncorrupted image. Experimental results demonstrate that the watermark is robust to several signal processing techniques, including JPEG compression, low pass and median filtering, histogram equalization and stretching, dithering, addition of Gaus

15、网络环境中对多媒体数据版权保护问题的解决方法而被提出，它使得紧密联系一段数据文件代码来鉴别数据的创建者、所属者、授权用户等成为了可能。本文提出了一种新的数字图像水印算法：在频域中，往已选择的 DCT 系数集合中嵌入一段实数伪随机序列，这样，根据人眼的视觉隐蔽特性而把水印掩藏在图片中，从而保证水印的隐藏。利用嵌入的随机序列的统计特性很容易的提取出水印，而不用依靠完整的原始图像。实验表明，这种水印技术对于常见的 JPEG 压缩、低通和中值滤波、直方图均衡和展缩、抖动、加高斯噪声、尺度变换及多水印等信号处理技术有很好的鲁棒性。关键字：关键字：数字水印；版权保护；安全性；图像认证2、 英文原文：英文原
16、文：TRANSPARENT ROBUST IMAGE WATERMARKINGAbstractWe propose a watermarking scheme to hide copyright information in an image. The scheme employs visual masking to guarantee that the embedded watermark is invisible and to maximize the robustness of the hidden data. The watermark is constructed for arbitrary image blocks by filtering a pseudo-n
