代码说明:

  dct隐写技术matlab实现资料。算法原理:通过在一个图像块中调整两个DCT系数的相对大小,隐藏秘密信息。 将载体图像分为8×8的块,做二维DCT变换 用来表示选中的两个系数的坐标对于第i bit秘密信息 if(要隐藏信息‘1’) make else make 逆DCT变换,还原图像 (dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)

  • Dynamicallyforecastingnetworkperformanceusingthene
    网络服务正在更新换代并且可扩展设备被设计成可提供在元计算环境中动态资源行为预测。这篇文章里,我们描述了预测产生的的设计和预测行为的细节。当预测方式为普通方式时,我们关注与他对TCP/IP端到端吞吐量能力的预测和在不同地点使用不同系统会带来的延迟量。因为在元计算软件的基础上网络预测需要计划的支持和质量服务保证的提高。(The Network Weather Service is a generalizable and extensible facility designed to provide dynamic resource performance forecasts in metacomputing environments.In this paper,we outline its design and detail the predictive performance of the forecasts it generates. While the forecasting methods are general,we focus on their ability to predict the TCP/IP end-to-end throughput and latency that is attainable by an application using systems located at differentsites.Such network forecasts are needed both to support scheduling (Bermanetal.,1996)and,by the metacomputing software infrastructure,to develop quality-of-service guarantees(DeFantietal.,to appear Grimshawetal.,1994). )
