《Linux编程白皮书》是由一群Linux高手所写的，它由五个部分组成――是Linux文档工程的一个印刷版本。该书描述了关键的设计概念，以及系统和Linux内核子系统的概念系统结构和具体的系统结构。全书是从Linux操作系统的心脏――内核开始进行深入介绍的。所介绍的知识包括Linux硬件和软件基础、内核机制、进程、模块、结构及源代码、Linux内核模块编程指南，把应用程序移植到Linux下，以及对网络的讨论等等。-"Linux programming White Paper" is written by a group of Linux experts, it consists of five parts-- the Linux Documentation Project is a print version. The book describes the key design concepts, and systems and subsystems of the Linux kernel structure and the concept of specific systems architecture. The book is from the heart of the Linux operating system-- starting core in-depth about. Introduced by the knowledge including Linux hardware and software infrastructure, the core mechanisms, processes, modules, the structure and source code, the Linux kernel module programming guide, applications to Linux, as well as the network discussions.

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 -A wavelet-based image digital watermarking algorithm that the algorithm will be mutually orthogonal two watermarks (watermark robust watermarking and reference) at the same time added to the carrier after image after DWT wavelet coefficients, and then using wavelet transform has been Add a watermark image to use to extract a reference to estimate the watermark image by the attacks, as a result of the robust watermark extracted suffered attacks and the reference watermark by the same attack, it can be estimated through the original Robust Watermarking of the embedded watermark image by adding noise, filtering, compression and cutting, such as a large number of image processing such as testing, can correctly detect the watermark, show that the algorithm has good
