摘要： A method and apparatus for generating discriminant functions for distinguishing obscene videos by using visual features of video data, and a method and apparatus for determining whether videos are obscene by using the generated discriminant functions, are provided. The method of generating discriminant functions includes: creating a first frame set by extracting a predetermined number of frames for each video data unit from a group of video data classified as obscene or non-obscene, and creating a second frame set by selecting the frames; generating a frame based discriminant function by extracting visual features of frames of the second frame set, and then generating a first discriminant value by determining whether each frame of the first frame set contains obscene video data; generating a group frame based discriminant function by extracting visual features of a group of frames of the first frame set, and then generating a second discriminant value by determining whether the frames of the group contain obscene video data; and generating a synthetic discriminant function by using the first and second discriminant values as a representative value of the video data. Accordingly, obscene video data stored in a computer system can be automatically and accurately distinguished.
摘要翻译：提供一种用于通过使用视频数据的视觉特征来产生用于区分淫秽视频的判别函数的方法和装置，以及用于通过使用所生成的判别函数来确定视频是淫秽的方法和装置。产生判别函数的方法包括：通过从分类为淫秽或非淫秽的一组视频数据中提取每个视频数据单元的预定数量的帧来创建第一帧集合，并通过选择帧来创建第二帧集合; 通过提取第二帧集合的帧的视觉特征，生成基于帧的判别函数，然后通过确定第一帧集合的每个帧是否包含淫秽视频数据来生成第一判别值; 通过提取第一帧集合的帧组的视觉特征，生成基于组帧的判别函数，然后通过确定该组的帧是否包含淫秽视频数据来生成第二判别式值; 以及通过使用第一和第二判别值作为视频数据的代表值来产生合成判别函数。因此，可以自动且准确地区分存储在计算机系统中的淫秽视频数据。

摘要： A method and a device for discriminating an obscene video using a time-based feature value are provided. The method includes: forming a first time-based flow of predetermined feature values varying with the lapse of time from one or more types of videos which are normalized with a first time interval; extracting a feature value varying with time from an input video of which obsceneness is to be determined and which is normalized with a second time interval, and forming a second time-based flow of the extracted feature value; and determining the obsceneness of the input video by calculating a loss value between the first time-based flow and the second time-based flow. The videos such as movies and dramas in which many persons appear have different obscenity characteristics from that of pornography, so it is possible to enhance reliability in determination of obsceneness.
摘要翻译：提供了一种使用基于时间的特征值来辨别淫秽视频的方法和设备。该方法包括：从以第一时间间隔归一化的一个或多个类型的视频形成随时间流逝而变化的预定特征值的第一时间流; 从要被确定淫秽的输入视频中提取随时间变化的特征值，并且以第二时间间隔被归一化，以及形成所提取的特征值的第二基于时间的流; 以及通过计算所述第一基于时间的流和所述第二时间流之间的损失值来确定所述输入视频的猥亵性。许多人出现的电影和戏剧等视频与淫秽色情有不同的淫秽特征，因此有可能提高羞辱性的判断力的可靠性。

摘要： An adaptive security policy based scalable video service apparatus includes a video streaming server, an adaptive security policy server and a terminal. The video streaming server receives a service demand via a network and generates an encrypted streaming data. The adaptive security policy server analyzes a media structure and the service demand, by using a service profile received from the video streaming server, so as to generate a security policy description. The terminal generates and transmits the service demand to the video streaming server or the adaptive security server, obtains the encrypted streaming data from the video streaming server and decrypts the encrypted streaming data for playback, storing and retransmission.
