  • Patent number: 8169481
    Abstract: A multi-perspective context sensitive behavior assessment system includes an adaptive behavior model builder establishing a real-time reference model that captures intention of motion behavior. It operates by modeling outputs of multiple user defined scoring functions with respect to multiple references of application specific target areas of interest. The target areas have criticality values representing a user's preference regarding the target areas with respect to one another. The outputs of the scoring functions are multiplied by the critically values to form high level sequences of representation that are communicated to the user.

  • Patent number: 7840515
    Abstract: The intelligent, automated surveillance system collects the interactions between the security personal and the surveillance system during the handling of an alarm. Each alarm is modeled as a “transaction” and each operation/action that a security personal executes modeled as an “event” within the transaction. The collected events within the transaction are in partial order. Furthermore, the system provides a scoring system for a security manager to evaluate the performance of the security guard. The score of the sequence of actions that the security guard performed manually and the system performed automatically for each set of dependent alarms are used to decide future sequence of operation. Security guards can overwrite the automatic sequencing of actions with manual sequence of operations.

  • Patent number: 7610604
    Abstract: A resource manager transforms the MPEG7 descriptors into an active and composite storage, processing, and presentation component in a storage area network (e.g. iSCSI). The active component can enable fast search and retrival operation directly on the logical disk blocks which maps well with the multimedia video stream and images data. It can also support content addressable search on the video and image files and play the media blocks directly. In addition, it enables a dynamic configuration of a media processing function after it is loaded in an execution environment. The data block is moved from the iSCSI interface directly into processing modules and presentation modules via decoder, buffer, and constraint control units.

  • Patent number: 7599957
    Abstract: A metadata database adaptor for use with a surveillance and/or sensor system is capable of adapting metadata messages of varying formats according to needs of metadata databases. In other aspects, a metadata data model template can allow a user to define a data definition that is used to map user defined data with the metadata data model template to form XML data schema. Template mapping knowledge can then be applied for fast XML data schema to non-XML database schema generation without translation processing. In yet other aspects, an application domain template can allow a user to define a query definition that can then be processed with a mapping of the application domain template to translate Xpath, Xquery, or others to a database query.

  • Patent number: 7583845
    Abstract: An associative vector storage system has an encoding engine that takes input vectors, and generates transformed coefficients for a tunable number of iterations. Each iteration performs a complete transformation to obtain coefficients, thus performing a process of iterative transformations. The encoding engine selects a subset of coefficients from the coefficients generated by the process of iterative transformations to form an approximation vector with reduced dimension. A data store stores the approximation vectors with a corresponding set of meta data containing information about how the approximation vectors are generated. The meta data includes one or more of the number of iterations, a projection map, quantization, and statistical information associated with each approximation vector. A search engine uses a comparator module to perform similarity search between the approximation vectors and a query vector in a transformed domain.

  • Patent number: 7426743
    Abstract: A peer-to-peer camera sensor network is defined using intelligent cameras that employ iSCSI initiators and iSCSI targets to read and write data and to send control commands directly across the network as iSCSI blocks. Because data transfer rides on top of the internet protocol, cameras can be directly attached to the internet without requiring attachment to a host computer. Image data represented as video frames are mapped onto iSCSI data blocks and are shared among the cameras directly to form an efficient virtual block level video image frame storage that can be directly manipulated by multiple cameras without data replications. Transport of multiple streams, associated with scalable or multilevel MPEG encoding scheme for instance, are automatically sequenced and realigned as the iSCSI data blocks are time-aligned.

  • Publication number: 20080198159
    Abstract: The surveillance visualization system extracts information from plural cameras to generate a graphical representation of a scene, with stationary entities such as buildings and trees represented by graphical model and with moving entities such as cars and people represented by separate dynamic objects that can be coded to selectively reveal or block the identity of the entity for privacy protection. A power lens tool allows users to specify and retrieve results of data mining operations applied to a metadata store linked with objects in the scene. A distributed model is presented where a grid or matrix is used to define data mining conditions and to present the results in a variety of different formats. The system supports use by multiple persons who can share metadata and data mining queries with one another.
