It uses a cascade-structured face detector trained with AdaBoost to detect face.Integrated with a linear face tracker,searching region and rescaling levels of the detector are reduced,and thus detection speed is accelerated.

在层次型AdaBoost检测算法的基础上，结合提出的一种基于线性预测的人脸跟踪算法来缩小搜索空间，使得检测速度提高到24ms/帧。

Maximum likelihood detector is the optimal detector and has the best performance. The challenge of MLD is the high computational complexity. K-Best decoding algorithm has been proposed to reduce the computational complexity. K-Best decoder algorithm computes Partial Euclidean Distance and only keeps the best K nodes that have the smallest accumulated PEDs. After completing breadth-first tree search, we will have K leaves with the smallest PEDs.

最大相似度侦测法是公认最佳化的演算法，有著最好的侦测效能，但运算复杂度将会随著调变群集和传送天线数目大小而呈指数型增加。K-Best球型解码演算法因而被提出来，得到近似最大相似度侦测法的结果，解决最大相似度侦测法运算复杂度过高的问题。K-Best球型解码演算法在计算完部份欧几里德距离后，需要取最小K个值做为候选点，再往下层去找候选点。

我国钢轨的探伤主要采用超声波检测方法，设备主要有大型探伤车和小型探伤仪。

This dissertation will study how to increase the time resolution of scintillator TOF detector by investigating the under-building BESIII TOF detector.

本论文将以正在建设中的BESIII的TOF探测器为例，研究如何进一步提高TOF探测器的时间分辨能力。

The time diversity detector based on pulse confliction is used at each stage. Because it increases the processing gain of the user at each stage, the detector could achieve good performance.

该检测器使每级检测的用户的处理增益最大，从而提高了每个检测用户的平均处理增益，进而提高了系统的检测性能。

I was just taking her hand, to help her out of a car, and I knew it.

我只是握着她的手，扶她下车，但我知道这一切。

China and South Korea have excoriated Japan over its approval of new school books which they say whitewash the atrocities committed during Japanese occupation, and anti-Japanese protests have been held in Chinese cities. The lingering bitterness over Japan's past imperialism still threatens to mar relations between the big East Asian powers

中国和韩国强烈谴责日本通过新的中学历史教科书，他们认为这一教科书掩盖了日本在其占领期间所犯下的残酷暴行，反日抗议活动在中国数座城市发生，历史上日本帝国主义制造的痛楚无法被忘却，这有可能破坏东亚强国间的关系。
