  • Publication number: 20120170803
    Abstract: Embodiments of the disclosure provide for systems and methods for creating metadata associated with a video data. The metadata can include data about objects viewed within a video scene and/or events that occur within the video scene. Some embodiments allow users to search for specific objects and/or events by searching the recorded metadata. In some embodiments, metadata is created by receiving a video frame and developing a background model for the video frame. Foreground object(s) can then be identified in the video frame using the background model. Once these objects are identified they can be classified and/or an event associated with the foreground object may be detected. The event and the classification of the foreground object can then be recorded as metadata.

  • Publication number: 20120170802
    Abstract: Trajectory information of objects appearing in a scene can be used to cluster trajectories into groups of trajectories according to each trajectory's relative distance between each other for scene activity analysis. By doing so, a database of trajectory data can be maintained that includes the trajectories to be clustered into trajectory groups. This database can be used to train a clustering system, and with extracted statistical features of resultant trajectory groups a new trajectory can be analyzed to determine whether the new trajectory is normal or abnormal. Embodiments described herein, can be used to determine whether a video scene is normal or abnormal. In the event that the new trajectory is identified as normal the new trajectory can be annotated with the extracted semantic data. In the event that the new trajectory is determined to be abnormal a user can be notified that an abnormal behavior has occurred.

  • Publication number: 20120154599
    Abstract: Systems, methods, and devices are disclosed for determining a zooming factor for a camera in a pan, tilt, and zoom (PTZ) camera tracking system to enable a camera to keep an object at a constant size within the camera's viewing area, despite changes in the object's distance from the camera. This provides a complement to a camera's pan and tilt tracking of the moving object. For example, a PTZ camera tracking system that determines an object to track, utilizes information regarding images of the object of interest are used to determine a zooming factor (or other zooming value) for a camera in the PTZ camera tracking system. This information includes variables such as tilt angles of one or more cameras and a reference zooming factor.

  • Patent number: 8173904
    Abstract: An adapter for use between a two-hole blade end fitting of a line post insulator arm and a Y-clevis bolt eliminates the need to replace the entire insulator arm when the end fitting fails or becomes distorted due to wear of the Y-clevis bolt. The adapter includes a body with a two-hole insulator end that connects to the end fitting and a single or double eye conductor end that supports the Y-clevis bolt. The conductor end is configured to align the load axis of the insulator arm with the Y-clevis bolt to transfer the tension load effectively through the adapter. Annular shoulders surround the two holes in the adapter back and the insulator end of the body. The shoulders extend into the bolt holes in the end fitting to center the bolts and form a clamp on the blade end to prevent further damage to the end fitting.
