【Graph program】 signature DL : 0: 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.

【matlab】 Wavelet-Decomposition-For-Images DL : 0: main executing reference usage: observeWaveletDecompositionBenchmark_N_levels.m The objective is to illustrate wavelet decomposition, and to describe how operations may be done in the wavelet domain before the reconstruction. The demo decouples the wavelet operations (transform, operation in wavelet domain, and reconstruction) from the plotting. A PSNR and MSE describes the possible distortion (however minimal) of the forward and inverse wavelet transform. * Caveat: The image display may be subjected to the selected target image. The objective is to provide a simple framework for the understanding of working with wavelets.

【Special Effects】 4paper4 DL : 0: 图像质量评价方法研究进展：图像质量评价是图像处理领域的研究热点。该文综合论述了图像质量的主观和客观评价方法，重点阐述了单视点图像质量的客观评价方法。对目前比较常用的峰值信噪比和均方误差全参考评价算法进行了分析并指出其存在的问题。然后，对基于误差敏感度和基于结构相似度的评价算法进行了论述和分析，并对质降和无参考评价方法进行了综述。根据视点的个数，图像质量评价可分为对传统单视点图像和立体图像的评价。该文还对立体图像质量评价算法进行了分析讨论。最后，就图像质量评价算法的进一步发展提出了若干技术与研究方向的展望。-Image Quality Assessment (IQA) is a hot research area in the field of image processing. In this paper, objective and subjective IQA methods are reviewed, and more attention is paid to the former. PSNR and MSE, which are commonly used to assess the quality, are analyzed in detail and their defects are given. The models based on error sensitivity and structure distortion of images are two critical methods in IQA, and the survey presents their key techniques and challenge problems. The reduced reference and no reference methods are also presented in this survey. Based on the number of view, IQA are classified into two major categories, namely, monoscopic image IQA and stereoscopic image IQA. This survey also makes an introduction of the stereoscopic image IQA. Finally, the survey lists several perspective sub-fields and topics in IQA progress.

【matlab】 fr_psnr DL : 0: PSNR is used to measure the difference between two images. It is defined as PSNR = 20 * log10(b/rms) where b is the largest possible value of the signal (typically 255 or 1), and rms is the root mean square difference between two images. The PSNR is given in decibel units (dB), which measure the ratio of the peak signal and the difference between two images. An increase of 20 dB corresponds to a ten-fold decrease in the rms difference between two images.
