Zigbee是IEEE 802.15.4协议的代名词。根据这个协议规定的技术是一种短距离、低功耗的无线通信技术。这一名称来源于蜜蜂的八字舞，由于蜜蜂(bee)是靠飞翔和“嗡嗡”(zig)地抖动翅膀的“舞蹈”来与同伴传递花粉所在方位信息，也就是说蜜蜂依靠这样的方式构成了群体中的通信网络。其特点是近距离、低复杂度、自组织、低功耗、低数据速率、低成本。主要适合用于自动控制和远程控制领域，可以嵌入各种设备。简而言之，ZigBee就是一种便宜的，低功耗的近距离无线组网通讯技术。
Zigbee is synonymous with the IEEE 802.15.4 protocol. According to the agreement of the technology is a short distance, low-power wireless communication technology. The name comes from the bee character dance, as bees (bee) is flying by and the " buzz" (zig) shake the wings of the " dance" to transfer pollen with peers where the position information in such a way that bees rely on constitute a group communication network. Its characteristics are close, low-complexity, self-organizing, low power, low data rate, low cost. Mainly suitable for automatic control and remote control, can be embedded in various devices. In short, ZigBee is a cheap, low-power short-range wireless network communication technology group. (2011-10-07, PDF, 269KB, 下载12次)

针对彩色图像提出了一种基于肤色和模板的人脸检测方法, 由肤色分割、模板匹配和人工神经网验证3 部
分组成. 首先使用HS I 空间的肤色统计模型分割出可能包含人脸的区域, 然后使用平均脸模板匹配和人工神经
网验证的方法在这些区域中搜索人脸. 该方法将彩色图像的肤色信息和灰度图像的模板匹配及人工神经网分类
模型综合起来, 既极大地提高了速度, 又具有较强的鲁棒性. 实验结果表明, 该算法是快速而有效的.
For color images is presented based on color and template face detection methods, from the color segmentation, template matching and artificial neural network validation three parts.
