摘要:
A system for information discovery of items, such as individuals or objects, from video-based tracks. The system may compute similarities of characteristics of the items and present the results in a matrix form. A similarity portrayal may have nodes representing the items with edges between the nodes. The edges may have weights in the form of vectors indicating similarities of the characteristics between the nodes situated at the ends of the edges. The edges may be augmented with temporal and spatial properties from the tracks which cover the items. These properties may play a part in a multi-objective presentation of information about the items in terms of a negative or supportive basis. The presentation may be partitioned into clusters which may lead to a merger of items or tracks. The system may pave a way for higher-level information discovery such as video-based social networks.
摘要:
A system for obtaining data from various sources. The data may be organized into cluster sets of related items. Elements of various kinds may be pulled from the data. The elements may be put together into sets of clusters for each kind of elements. The clusters may be refined relative to one another and in view of integrated properties of the cluster sets. Elements may be added or removed from the clusters during refinement. Examples of the elements may be people and events. Examples of cluster sets of such elements may be groups and goals, respectively.
摘要:
An apparatus includes at least one memory unit and at least one processing unit. The memory unit is configured to receive and store information associated with a particular geographical region. The processing unit configured to execute a computer program for discretizing an image of the geographical region into a plurality of sub-regions. Using these sub-regions, the processing unit may generate a graph comprising a plurality of nodes and a plurality of edges in which the nodes comprise the sub-regions. The processing unit may also geospatially partition an image of the geographical region according to the information that is associated with each of the sub-regions.

摘要:
A system for social network construction. Video analytics and association may be used to develop a social network. Also, social groups may be developed from temporal proximity of persons. In the case of several social networks, they may be collapsed into one network or a weighted graph that mining algorithms can handle.
摘要:
A framework for state estimation using multi-network observation. Highly scalable qualitative probabilistic algorithms may be used to combine noisy, uncertain outputs having multi-modal event data from numerous networks into a relatively accurate and coherent estimate of the system state. Models of disparate networks may be pulled together to result in unified multi-modal event data. Information from multiple networks may be graphed and analyzed.
