摘要： A system and method for associating users with a micro-community that is relevant to an object reference. The object reference is anything that can be perceived either physically or conceptually, such as a location, a document, a calendar entry, a document, a news feed, a biometric key, an image, a news feed, etc. A micro-community engine identifies users who are associated explicitly with the object reference as well as people who would be interested in the object implicitly and associates them with a micro-community. The micro-community engine provides an intuitive and flexible means for communication between members of the micro-community.

摘要： A method of establishing a communications link uses automatic sensing of a computer user's presence and activity state to record user attributes in a form accessible to other computers in a communications network. Such automatic sensing may include keyboard/mouse monitors, cameras with associated image processing algorithms, speech detectors, RF radiation detectors, and infrared sensors. Preferably, the attribute recording is done in a server process which can be accessed by other computer programs. A first application of this method is to inform persons at remote locations whether the party to be called is available to receive a call. A second application of the method is to use a Connection Agent to determine whether all desired participants for a conference, or at least a quorum of them, are present and available, so that the conference can be started. A third application of the method is to allow a called party to adjust the kind of notification, if any, he or she receives of an incoming call, depending upon what activity is currently engaging the called party.

摘要： A computer implemented method models a scene in a video acquired by a camera. For each pixel in each frame of the video, a time series of intensities of the pixel is acquired. A harmonic series is extracted from samples of each time series using a sliding window. Distances between the harmonic series are measured. The distances are an estimate of spectral components in an autocorrelation function of underlying dynamic processes in the scene.

摘要： A method determines temporal patterns in data sequences. A hierarchical tree of nodes is constructed. Each node in the tree is associated with a composite hidden Markov model, in which the composite hidden Markov model has one independent path for each child node of a parent node of the hierarchical tree. The composite hidden Markov models are trained using training data sequences. The composite hidden Markov models associated with the nodes of the hierarchical tree are decomposed into a single final composite Markov model. The single final composite hidden Markov model can then be employed for determining temporal patterns in unknown data sequences.

摘要： Binary motion events are detected by individual motion sensors placed in a physical environment. The motions events are transmitted to a cluster leader, each motion detector being a cluster leader of immediately spatially adjacent motion sensors. Movements of objects are detected by the cluster leaders according to the motion events. The movements are transmitted to supercluster leaders, each motion detector being a supercluster leader of immediately spatially adjacent motion clusters of sensors. Activities of the objects are detected by the supercluster leaders, and actions of the objects are detected according to the activities.

摘要： A method and apparatus acquires images of a scene with an omni-directional imager and a pan-tilt-zoom imager. A relationship between pixels in the input image and locations in the scene is expressed in terms of polar coordinates. An event is detected in the input images and the omni-directional pan-tilt-zoom camera is directed at the event in the scene using the relationship expressed in the polar coordinates.

摘要： A method for querying a surveillance database stores videos and events acquired by cameras and detectors in an environment. Each event includes a time at which the event was detected. The videos are indexed according to the events. A query specifies a spatial and temporal context. The database is searched for events that match the spatial and temporal context of the query, and only segment of the videos that correlate with the matching events are displayed.

摘要： A surveillance system detects events in an environment. The system includes a camera arranged in the environment, and multiple context sensors arranged in the environment. The sensors are configured to detect events in the environment. A processor is coupled to the camera and the context sensors via a network. The processor provides the camera with actions based only on the events detected by the context sensors. The actions cause the camera to view the detected events.

摘要： A method models movement of users in an environment including sensors connected in a network. Events due to movement of the users are detected at the sensors and each event is labeled according to a particular sensor and time of the event. The events for each sensor are summed into a corresponding histogram time interval bin. A plurality of co-occurrence matrices are generated from the histograms according to C i , j , δ = ∑ t = 0 T ⁢   ⁢ H i , t ⁢ H j , t + δ , where i and j represent each possible pair of sensors, δ represent time-off-sets, T is a total time for the detecting, t represents a particular time, and H represents the histogram time interval bins. The co-occurrence matrices can be used to determine a geometry of the network, and for predicting future activities signaled by terminating events.
