45326 在回顾了当下流行的基于深度网络的行为识别方法的基础上，着重综述了基于手动提取特征的传统行为识别方法。 After a brief review of the current popular behavior recognition method based on deep network, it focused on the traditional behavior recognition methods.
45327 传统行为识别方法通常遵循对视频提取特征并进行建模和预测分类的流程， Traditional behavior recognition methods usually followed the processes of video feature extraction, modeling of features and classification.
45328 并将识别流程细分为以下几个步骤进行综述：特征采样、特征描述符选取、特征预/后处理、描述符聚类、向量编码。 Following the basic process, the recognition process was overviewed according to the following steps, feature sampling, feature descriptors, feature processing, descriptor aggregation and vector coding.
45329 同时，还对评价算法性能的基准数据集进行了归纳总结。 At the same time, the bench-mark data set commonly used for evaluating the algorithm performance was also summarized.
45330 基于软件定义网络（SDN, software defined networking）技术构建网络试验床（简称 SDN 试验床）近年来引起了学术界和产业界的广泛关注，并出现了很多具有参考价值的系统平台建设案例。 The network tested based on software defined networking (referred as SDN tested) has attracted extensive attention in the academic and industrial circles in recent years, and there have been many valuable cases of system/platform construction.
45331 因此，针对全球范围内的 SDN试验床进行综述研究， Therefore, an overview of the SDN tested was intended to conduct in the global scope.
