AUTOMATIC MOVEMENT DETECTION APPLIED TO A TELEVISION SURVEILLANCE SYSTEM

摘要

This note describes an automatic movement detection system for use in conjunction with a television surveillance system. Any movement, or change in illumination, occurring in the scene under surveillance, causing a change in the picture being transmitted, results in alarm being raised. Features include a method of reducing the likelihood of false alarms and a means of matching detection sensitivity to the likely rate of movement of any person or object.
