摘要： A method for recommending a video content to a viewer. The method including the steps of: determining a user profile of the viewer, the user profile indicating the viewing preferences of the viewer, providing a plurality of user profiles; comparing the user profile of the viewer to each of the plurality of user profiles to determine if each of the plurality of user profiles contains at least one common characteristic with the user profile of the viewer; and determining a recommendation for the video content based on the plurality of user profiles, wherein user profiles having the at least one common characteristic are assigned a greater recommendation weight than user profiles not having the at least one common characteristic.

摘要： A telephone user who is at a first telephone station and is placed on hold at a second station is prevented from listening to an objectionable audio signal while a call is in process between the user and the second telephone station. The objectionable audio signal is detected while the call is in process and the user is prevented from hearing the objectionable audio signal while the objectionable audio signal is being detected. In response to detection of the end of the objectionable audio signal, the user is coupled to the second telephone station.

摘要： A method and apparatus are disclosed for classifying objects using a hierarchical object classification scheme. The hierarchical object classification scheme provides candidate classes with an increasing degree of specificity as the hierarchy is traversed from the root node to the leaf nodes. Each node in the hierarchy has an associated classifier, such as a Radial Basis Function classifier, that determines a probability that an object is a member of the class associated with the node. The nodes of the hierarchical tree are individually trained by any learning technique, such as the exemplary Radial Basis Function Network, that uses appearance-based information of the objects under consideration to classify objects. A disclosed recognition scheme uses a decision criterion based upon recognition error to classify objects.

摘要： A video content analysis system extends content analysis capability of one system to multiple channels by providing for the spatial multiplexing of the multiple channels and appropriately analyzing the spatially multiplexed video signal. The resulting system may be lower in cost that present systems and permit the system to work with ancillary equipment such as video recorders. The system also preserves the real-time information inherent in the multiple source signals.

摘要： A monitoring system for an infant, child, invalid, or other person requiring care uses computer vision and hearing, and inputs of other modalities, to analyze the status of a caretaker and/or cared-for person and its environment. The conditions are classified as normal or alarm conditions and an informative alarm signal is generated which may include records of the vision audio and other inputs. The system also has the ability to solicit responses from the occupants to stimulate a classifiable input to reduce ambiguity in its state signal.

摘要： A camera system comprising a camera, a monitor, an image detector, a touch screen, and a remote control. The monitor displays a field of view of a lens of the camera. The image detector provides a viewer image to the remote control whereby the remote control can determine a desired image within the field of view that the viewer is gazing upon. The touch screen enables a viewer of the monitor to point to the desired image of the field of view and provides signal(s) indicative of the pointing. The remote control is operable to activate various drives to pan and/or tilt the camera, or to zoom and/or focus the lens to the desired image and to follow any movement of the image within the field of view.

摘要： Methods and apparatus are disclosed for tracking an object of interest in a video processing system, using clustering techniques. An area is partitioned into approximate regions, referred to as clusters, each associated with an object of interest. Each cluster has associated average pan, tilt and zoom values. Audio or video information, or both, are used to identify the cluster associated with a speaker (or another object of interest). Once the cluster of interest is identified, the camera is focused on the cluster, using the recorded pan, tilt and zoom values, if available. An event accumulator initially accumulates audio (and optionally video) events for a specified time, to allow several speakers to speak. The accumulated audio events are then used by a cluster generator to generate clusters associated with the various objects of interest. After initialization of the clusters, the illustrative event accumulator gathers events at periodic intervals. The mean of the pan and tilt values (and zoom value, if available) occurring in each time interval are then used to compute the distance between the various clusters in the database by a similarity estimator, based on an empirically-set threshold. If the distance is greater than the established threshold, then a new cluster is formed, corresponding to a new speaker, and indexed into the database. Fuzzy clustering techniques allow the camera to be focused on more than one cluster at a given time, when the object of interest may be located in one or more clusters.

摘要翻译： 公开了使用聚类技术来跟踪视频处理系统中的感兴趣对象的方法和装置。 区域被划分为近似区域，被称为簇，每个区域与感兴趣对象相关联。 每个群集都具有关联的平移，倾斜和缩放值。 音频或视频信息或两者都用于识别与扬声器（或另一个感兴趣对象）相关联的群集。 一旦识别出感兴趣的群集，相机就会聚焦在群集上，使用记录的平移，倾斜和缩放值（如果可用）。 事件累加器最初在指定时间内累积音频（和可选的视频）事件，以允许多个扬声器发言。 然后，集群生成器使用累积的音频事件来生成与感兴趣的各种对象相关联的集群。 在集群初始化之后，说明性事件累加器以周期性间隔收集事件。 然后，使用每个时间间隔内出现的平移和倾斜值（和缩放值，如果可用）的平均值，基于经验设定的阈值，通过相似度估计器计算数据库中的各种群集之间的距离。 如果距离大于建立的阈值，则形成一个新的集群，对应一个新的发言者，并将其编入数据库。 当感兴趣对象可能位于一个或多个集群中时，模糊聚类技术允许相机在给定时间聚焦在多于一个集群上。
