变化检测的阈值设定

应用背景最近写的一个DS18B20进行温度测试程序，应用在Zigbee模块CC2530上。DS18B20采用单总线传输方式，应用中能够最小化利用片上那个资源。关键技术CC2530 是用于2.4-GHz IEEE 802.15.4、ZigBee 和RF4CE 应用的一个真正的片上系统（SoC）解决方案。它能够以非常低的总的材料成本建立强大的网络节点。DS18B20是常用的温度传感器，具有体积小，硬件开销低，抗干扰能力强，精度高的特点。  

pso程序的源代码 pso程序的源代码-粒子群优化算法源程序 作者：FashionXu 一个pso程序的源代码。在vc.net2003下面通过。 建议：看代码之前，请先弄明白pso是怎么回事。然后请对应着来：程序中用Agent代表一只鸟，PSO代表鸟群。阅读源代码，不要顺着看，先看main(),然后按照出现的东西的顺序，一个一个得来，呵呵，纯粹是建议。-PSO program

请注意一个凸函数的域是由数据流凸 set.can 等效地对被核查 设置 S0。这尤其是具有重大的现实意义

可以识别图片中火焰区域，目前支持jpg和bmp格式图片。主要根据火焰的颜色来识别，同时结合火焰的边缘轮廓特征。对于视频中的火焰识别，已经在界面中添加了接口，后续还需要完善，识别的算法是一样的，需要解析视频后，将每一帧作为一个单独的图片来识别

Exceptional C++ shows by example how to go about solid software engineering. Along with a lot of other material, this book includes expanded versions of the first 30 issues of the popular Internet C++ feature Guru of the Week (or, in its short form, GotW), a series of self-contained C++ engineering problems and solutions that illustrate specific design and coding techniques.

应用背景JPHide 和JPSeek 的源代码！JPHide&JPSeek是一个JPEG图像的信息隐藏软件！-JPHide and JPSeek source code! JPHide & JPSeek is a JPEG image information hidden software!关键技术JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the e
