Simply speaking, stealth technology allows an aircraft to be partially invisible on radar or any other detection methods.
简单来讲，隐形技术可以使飞机在雷达或其他检测方法下变得部分不可见。
Other detection methods are based on the statistics of IP addresses and the length of data packets, but their detection accuracy declines rapidly under the IP spoofing attack.
另一些方法基于IP地址和数据报长度的统计特征，但这些方法在IP地址欺骗攻击时检测率急剧下降。
The algorithm reduces the range where faces are to be searched, therefore its detection speed is three times of that of other detection methods used singly by multi-template matching.
这种算法大大减小了搜索人脸的范围，使得检测速度比单纯仅用多模板匹配来检测人脸提高了三倍多。
