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

Description: 使用纹理坐标，用简单的方法绘制漂亮的水面，水波使用了正弦函数和加入噪声的方法-Still using texture coordinates, this time here is a very simple way to render fancy water. Waves are shaped using both a sinus function and some Perlin noise. The same texture is used for both fake reflection and transparency, using texture spherical coordinates. Tweaking the texture may lead to quite a good result I think.
Use left click to rotate, and right click to translate. You can also switch to wire-frame rendering using L, and get back using P or F. N toggles normals rendering.

Description: Video compression standards follow certain principles for frame identification based on Group of Pictures (GOP). It was observed that instead of following the pre-coded GOP, if frames are adaptively chosen based on simple matching criteria, further processing could be effectively done. It was also noted from the earlier techniques that the presence of B-frames leads to buffering of the memory within the past and future frames during the coding stage. The computational time increases with more number of B-frames. Hence, a novel framework has been emphasized in the present investigation firstly for adaptive frame identification and secondly, replacing B-frames with either I-frames or P-frames using NSEW Affine Translation for the purpose of video compression. The result shows that the performance objective evaluation coincides with the subjective evaluation.
