Measurement of complex quantity of monitoring area and detection of high active part of invading object in complex background for surveillance camera system

Abstract

Surveillance camera system is one of security system. And, general surveillance camera system consists of surveillance camera installed in the monitoring area, and video monitor in the administrative room, and connects each device with communication line. An observer can always watch the monitoring area in the distant place by the networking of the surveillance camera system. Therefore, the observer needs to always watch large amount of image data surveillance camera photographed. It is necessary for it to spend much time and labor that an observer confirms only by naked eyes. This study measures how complex an image is with numerical value from 0.0 to 1.0 using Complex Quantity. The proposal method detects complex background from the image which surveillance camera photographed, and shows enlarges complex background so that an observer can find suspicious individual or unidentified object hiding in complex background easily. And, we measure livingness of the movement of object invading the complex background with Active Quantity so that an observer is able to watch the movement of the subject in monitoring area efficiently. Active Quantity measures how active the movement of the object is with numerical value from 0.0 to 1.0 quantity. And, the proposal surveillance camera system detects high active part consisting of high Active Quantity from the movement of the object in complex background. The observer is possible to watch the quick movement of objects hiding in the complex background in the monitoring area using the proposal surveillance camera system.
