Finally, on Earth-space paths, by applying a modification of the Rytov method that incorporates spatial frequency filter function under strong fluctuation conditions, a tractable model is developed for the scintillation index of a Gaussian optical beam wave that is valid under moderate-to-strong irradiance fluctuations. The scintillation indexes for collimation Gaussian beam are predicted by this analytic model, based on ITU-R C〓 model.

最后，应用强起伏下引入空间滤波函数的修正Rytov方法，发展了一种易处理且可用于从弱到强起伏地－空路径的高斯波束光波闪烁指数模型；基于ITU-RC〓模型，预测了准直高斯波束的闪烁指数，其结果和理论分析结果相符。

By using particle filter method based on Incremental Principal Component Analysis, this system incrementally learns a low dimensional eigenspace representation of the tracking results to reflect appearance variation of the target object.

该系统利用基于增量式主成分分析的粒子滤波方法增量式地学习一个表示跟踪结果的低维特征空间，以反映目标物体的外观变化。

At first, the AdaBoost is used to detect human faces in the video, then the detected faces are normalized and projected to the incremental eigenspace to obtain their vector representation.

首先通过AdaBoost检测视频序列中的人脸图像，将检测到的人脸做标准化处理后投影到增量特征人脸子空间中，得到人脸图像的向量表述；然后应用单类支持向量机进行训练和分类，根据分类的结果动态地调整前面得到的最优分类超平面，实现对电影视频中特定演员的检索功能。
