METHOD AND APPARATUS FOR EFFICIENT AND FLEXIBLE SURVEILLANCE VISUALIZATION WITH CONTEXT SENSITIVE PRIVACY PRESERVING AND POWER LENS DATA MINING

摘要

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.
