通用无线分组业务(GPRS) 是一种基于全球移动通信系统(GSM) 的无线分组交换技术, 提供
端到端的、广域的无线IP 连接, 具有永远在线等特点。介绍了基于GPRS 网络的数据终端单元
(DTU) 。该单元是由以ARM芯片S3C44B0X 和GPRS 模块G20 为核心的硬件和软件组成。在概括
工业GPRS 监控系统构成的基础上, 介绍了GPRS DTU 硬件设计, GPRS DTU 软件是由μC /OSⅡ操
作系统、TCP / IP 协议、点对点协议组成。该单元使用户通过GPRS 网络实现用户设备和用户数据
中心之间的数据传输-General Packet Radio Service (GPRS) is based on Global System for Mobile Communications (GSM) wireless packet switching technologies to provide end-to-end, wide-area wireless IP connection, with always-on and so on. Presented data based on the GPRS network terminal unit (DTU). The unit is the ARM chip from S3C44B0X and GPRS Module G20 as the core hardware and software components. In the summary of the industrial composition of GPRS monitoring system based on GPRS DTU introduces hardware design, GPRS DTU software by μC/OS Ⅱ operating system, TCP/IP protocol, the composition of point-to-point agreement. The unit allows users to users through the GPRS network equipment and user data between the data center

一个感兴趣的点检测方案，提出了可比的质量…
SURF算法是继SIFT算法后的又一图像不变特征检测算法，除了具有SIFT算法稳定高效的特点外，还极大的降低了SIFT算法复杂度，大大提高了特征检测和匹配的实时性。这里上传的SURF算法的实现源代码-An interest point detection scheme is presented that is comparable in quality to existing
methods, but can be performed much faster. The detection is based on a straightforward color
analysis at a coarse granularity.Testing confirms that this detection scheme is much faster than the state-of-the-art. It is
also repeatable, even under different viewing conditions. The detector is robust with respect to
changes in viewpoint, lighting, zoom, and to a certain extent, rotation.

迄今为止，本书已介绍了可在Microsoft Wi n d o w s操作系统中使用的全部网络A P I函数。
利用这些函数，我们的应用程序可通过网络，建立与其他程序的通信联系。在那些讨论中，
我们在很大程度上将重点放在七层O S I模型的应用层和表示层上面-date, The book has been introduced in the Microsoft Wi n d o w s operating system used in all network P A letter I few. Use these functions, we can process the application through the network and the establishment of procedures and other communications links. In those discussions, we will largely focus on the seven storeys I S O model layer and the application layer above said
