Description: 提出了一种基于小波域的图像数字水印算法·该算法将相互正交的两种水印(鲁棒水印和参考
水印)同时添加到经过DWT后的载体图像小波系数中,然后用小波反变换得到添加了水印的图像·用提取出
的参考水印来估计图像所受到的攻击,由于提取出的鲁棒水印所受的攻击与参考水印受到的攻击一样,因此
可以估计出原始的鲁棒水印·通过对嵌入水印的图像进行加入噪声、滤波、压缩以及裁剪等大量图像处理等试
验,均能正确检测出水印,表明该算法具有很好的感知效果和鲁棒性

Description: Matlab source code for DCT-based watermarking for grayscale images. DCT-based watermark recovering without resorting to the uncorrupted original image. Digital watermarking has been proposed as a viable solution to the need of copyright protection and authentication of multimedia data in a networked environment, since it makes possible to identify the author, owner, distributor or authorized consumer of a document.
A new watermarking technique to add a code to digital images is presented: the method operates in the frequency domain embedding a pseudo-random sequence of real numbers in a selected set of DCT coefficients. Watermark casting is performed by exploiting the masking characteristics of the Human Visual System, to ensure watermark invisibility. The embedded sequence is extracted without resorting to the original image, so that the proposed technique represents a major improvement to methods relying on the comparison between the watermarked and original images.

Description: 该目录包含了基于可移植的C语言的数字水印算法的代码。这些代码具有示范
性的意义，且有一定的鲁棒性。
需要安装NetPGM的程序包（用来存取pgm格式图像），然后才能在linux下面编译。
NetPGM是图像文件的输入/输出软件包。可以在网上搜索得到。我们已经对
256灰度级，512×512大小的图像进行了测试。程序编译后的调用格式如下（以encode为例）：
wm_cox_e -s cox.sig -o wm_image.pgm image.pgm
其中，-s表示要添加的水印信号，cox.sig是信号文件。
-o表示输出图像文件名为wm_image.pgm，
image.pgm为输入文件名。
几个辅助程序：
cmp_pgm 计算差分图像，PSNR等
cmp_dct 计算全帧DCT域的差分图像
cmp_dct8x8 计算8×8大小的DCT域差分图像
比如说，为了产生两个PGM图像的差分图像并计算它们的PSNR，命令如下：
cmp_pgm -p -i original.pgm -o diff.pgm watermarked.pgm
产生水印信号：
gen_cox_sig -o cox.sig
程序将产生适合512×512大小，8-bit灰度的pgm图像的水印信号。
水印提取：
wm_cox_d -s cox.sig -i lena.pgm -o cox.wm cox_lena.pgm
请注意，cox的算法需要原始图像做参考来提取水印，压缩后的水印将存储在cox.wm中。-This directory contains the C-based portable digital watermarking algorithm code. The code has a demonstration
Of meaning, and there is a certain degree of robustness.
NetPGM need to install the package (to access the pgm format images), and then to compile in linux below.
NetPGM is the image file input/output package. Can search by. We have already
256 gray level, 512 × 512 size images were tested.
Procedure call format, compiled as follows (in encode an example):
wm_cox_e-s cox.sig-o wm_image.pgm image.pgm
Which,-s that you want to add the watermark signal, cox.sig is the signal file.
-O said output image file name wm_image.pgm,
image.pgm for the input file name.
Several auxiliary programs:
cmp_pgm calculate the difference image, PSNR, etc.
cmp_dct full frame DCT domain calculation of difference image
cmp_dct8x8 calculate the size of 8 × 8 DCT domain differential image
For example, in order to produce two PGM images and calculate their differ Platform: |

Description: Digital watermark embeds informa-
tion bits into digital cover such as images and
videos to prove the creator’s ownership of his
work. In this paper, we propose a robust image
watermark algorithm based on a generative
adversarial network. This model includes two
modules, generator and adversary. Generator
is mainly used to generate images embedded
with watermark, and decode the image dam-
aged by noise to obtain the watermark. Adver-
sary is used to discriminate whether the image
is embedded with watermark and damage the
image by noise. Based on the model Hidden
(hiding data with deep networks), we add a
high-pass filter in front of the discriminator,
making the watermark tend to be embedded in
the mid-frequency region of the image. Since
the human visual system pays more attention
to the central area of the image, we give a
higher weight to the image center region, and
a lower weight to the edge region when calcu-
lating the loss between cover and embedded
image. The watermarked image obtained by
this scheme has a better visual performance.
Experimental results show that the proposed
architecture is more robust against noise
interference compared with the state-of-art
schemes. Platform: |
