Abstract

There are many CCTV cameras connected to the video surveillance and monitoring center for the safety of citizens, and it is difficult for a few monitoring agents to monitor many channels of videos. In this paper, we propose an intelligent video surveillance system utilizing a safety map to efficiently monitor many channels of CCTV camera videos. The safety map establishes the frequency of crime occurrence as a database, expresses the degree of crime risk and makes it possible for agents of the video surveillance center to pay attention when a woman enters the crime risk area. The proposed gender classification method is processed in the order of pedestrian detection, tracking and classification with deep training. The pedestrian detection and tracking uses Adaboost algorithm and probabilistic data association filter, respectively. In order to classify the gender of the pedestrian, relatively simple AlexNet is applied to determine gender. Experimental results show that the proposed gender classification method is more effective than the conventional algorithm. In addition, the results of implementation of intelligent video security system combined with safety map are introduced.

시민들의 안전을 위한 영상통합관제센터에는 수많은 CCTV 카메라가 연결되어 많은 채널의 영상을 소수의 관제사가 관제하는데 어려움이 있다. 본 논문에서는 많은 채널의 영상을 효과적으로 관제하기 위하여 안전지도와 연계한 지능형 영상보안 시스템을 제안한다. 안전지도는 범죄 발생 빈도를 데이터베이스로 구축하고, 범죄 발생 위험 정도를 표현하고, 범죄 취약 계층인 여성이 범죄 위험 지역으로 진입하면 영상통합관제센터의 관제사가 주목할 수 있도록 한다. 성별 구분을 보행자 검출 및 추적 그리고 딥러닝을 통하여 성별을 구분한다. 보행자 검출은 Adaboost 알고리즘을 이용하고, 보행자 추적을 위한 확률적 데이터 연관 필터(probablistic data association filter)를 적용한다. 보행자의 성별을 구분하기 위하여 비교적 간단한 AlexNet를 적용하여 성별을 판별한다. 실험을 통하여 제안하는 성별 구분 방법이 종래의 알고리즘에 비하여 성별 구분에 효과적임을 보인다. 또한 안전지도와 연계한 지능형 영상보안 시스템 구현 결과를 소개한다.
