摘要： Techniques for simulation of multi top-level graphical-containers (e.g., frames) in an object-oriented computing environment are disclosed. A Multi Top-level Graphical-Container Simulator (MTGS) can be provided to simulate multi top-level graphical container support for applications that expect to use a plurality of top-level graphical containers (e.g., frames, windows). A MTGS may be implemented as a layer between a GUI-based application and an operating system and/or hardware/device with limited or virtually no graphical support capability. The Multi Top-level Graphical Simulator (MTGS) can effectively isolate the operating systems and/or hardware/device from the GUI-based application, and yet hide this simulation from the operating system and/or hardware/device. MTGS may be implemented in a platform independent programming language (e.g., Java™ programming language using a set of Java™ classes which have been provided in the Java™ Swing development toolkit.

摘要： Through the association of an IP address with each data stream, a single system may be used by a network card or a tuner to select multicast IP data. Each data stream is identified by a unique IP address. More particularly, a locator adapted for identifying a data stream is associated with one of a plurality of data streams. The locator is then mapped to an IP address. When it is determined that the IP address corresponds to a data stream locator associated with a data stream, a tuner is instructed to read the data stream associated with the data stream locator. However, when it is determined that the IP address does not correspond to a data stream locator, a network card identified by the IP address is instructed to read data from the associated network. Since each data stream may be associated with a plurality of multicast IP addresses, a multicast group address is specified to identify the appropriate multicast IP data transmitted in the data stream. Packets addressed to the multicast group address may then be received by either a tuner or a network interface card.
摘要翻译： 通过IP地址与每个数据流的关联，网卡或调谐器可以使用单个系统来选择多播IP数据。 每个数据流都由唯一的IP地址标识。 更具体地，适于识别数据流的定位器与多个数据流中的一个相关联。 然后将定位器映射到IP地址。 当确定IP地址对应于与数据流相关联的数据流定位器时，指示调谐器读取与数据流定位器相关联的数据流。 然而，当确定IP地址不对应于数据流定位器时，指示由IP地址标识的网卡从相关网络读取数据。 由于每个数据流可以与多个多播IP地址相关联，所以指定多播组地址以识别在数据流中发送的适当的多播IP数据。 寻址到多播组地址的分组可以由调谐器或网络接口卡接收。

摘要： A method to provide automatic content-based video indexing from object motion is described. Moving objects in video from a surveillance camera 11 detected in the video sequence using motion segmentation methods by motion segmentor 21. Objects are tracked through segmented data in an object tracker 22. A symbolic representation of the video is generated in the form of an annotated graphics describing the objects and their movement. A motion analyzer 23 analyzes results of object tracking and annotates the graph motion with indices describing several events. The graph is then indexed using a rule based classification scheme to identify events of interest such as appearance/disappearance, deposit/removal, entrance/exit, and motion/rest of objects. Clips of the video identified by spatio-temporal, event, and object-based queries are recalled to view the desired video.

摘要： Object detection for scene change analysis is performed by a statistical test applied to data extracted from two images taken from the same scene from identical viewpoints. It is assumed that a single change region corresponding to an object that is present in one image but absence in the other is given. In the case of TV data, the test consists of measuring the coincidence of edge pixels in each image with the boundary of the change region. In the case of IR data, the tests consist of measuring the pixel intensity variance within the change region in each image.
摘要翻译： 用于场景变化分析的物体检测通过应用于从相同视点从相同场景拍摄的两幅图像提取的数据的统计测试来执行。 假设给出对应于存在于一个图像中但在另一个图像中不存在的对象的单个改变区域。 在TV数据的情况下，测试包括测量每个图像中的边缘像素与变化区域的边界的一致性。 在IR数据的情况下，测试包括测量每个图像中变化区域内的像素强度方差。

摘要： A monitoring apparatus (10) includes a video camera (12) with a section (16) that permits remote control of the camera. A computer 24 subjects video images from the camera to video processing (61-63), which includes temporal sampling, spatial sampling, and dithering. The processed image (71) is integrated into a document in hypertext mark-up language format. A portable unit (46) is operatively coupled to the computer through a wireless link (49), a cellular base station (36), and a network (38) or telephone line (41). An infrared sensor (19) can detect an event of interest in the monitored area, causing the computer to place a telephone call to the portable unit. The person possessing the portable unit can then use the portable unit to access the document which contains the processed image through the network, in order to observe or verify the event. The person can also use the portable unit to remotely control the operation of the video camera.
