UNITED STATES UTILITY PATENT APPLICATION SYSTEM AND METHOD FOR MONITORING VIRTUAL PERIMETER BREACHES

摘要

A video security system and method for monitoring active environments that detects a security-relevant breach of a virtual perimeter and can track a virtual perimeter breaching object to detect risk-relevant behavior of persons and objects such as loitering and parking, and provides fast and accurate alerts. The system is able to achieve advance alerts by monitoring an extended virtual perimeter. The image processing module of the system employs a deep learning neural network (DNN) for fast image processing. The system can further increase speed by reducing the image data that is being processed to data extracted from one or more reduced data sources including virtual perimeter zones, a delta of a series of image frames, and a representative image frame of a series of frames.
