[Graph programsignature

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
