Method And System For Metadata Extraction From Master-Slave Cameras Tracking System
First Claim
1. A method of enabling retrieval of information from a video surveillance system, the method comprising:
- automatically identifying an object of interest in a video scene of a master camera or a slave camera, the object of interest for the slave camera being determined as a function of metadata from the master camera;
automatically classifying at least one feature in the object of interest; and
storing a representation of the at least one feature in a form of metadata, including the metadata from the master camera to the slave camera, associated with video of at least the slave camera in a manner enabling retrieval of information about the object of interest.

Abstract
An embodiment of the present invention includes a master camera that may record master metadata regarding an object of interest and communicate the master metadata to a slave camera. The slave camera may zoom, pan, or tilt to isolate and record more detailed image data regarding the object of interest based on the master metadata. In addition, the slave camera may record slave metadata regarding the object of interest. The master and slave metadata may be stored associated with the recorded image data enabling a later search for the object of interest to be expedited. The recorded image data including the object of interest may be identified with greater ease as it may be guided by the master or slave metadata, or a combination thereof. According to embodiments presented herein, processing time for searching and identifying an object of interest may be reduced by enabling a search on the metadata associated with image data, rather than by searching the image data itself.

18. A system for enabling retrieval of information from a video surveillance system, the system comprising:
-
a master camera, a slave camera, and a server communicatively coupled; the master camera configured to identify an object of interest automatically in a video scene of the master camera or the slave camera and to communicate master classification information of the object identified in the form of metadata to the slave and to the server; the slave camera configured to determine more detailed slave classification information based on the master classification information communicated and to communicate the more detailed slave classification information in the form of metadata to the server; and the server configured to store the master classification information and the detailed slave classification information in a manner enabling retrieval of information about the object of interest. - View Dependent Claims (19, 20, 21, 22)
