최근 CCTV(Closed Circuit Television)의 설치가 증가하면서 효율적인 모니터링을 위하여 지능형 영상분석 기술에 대한 관심이 높아지고 있다. 지능형 영상분석 기술은 영상의 정보를 분석하여 자동으로 이상 행위를 탐지하고 관리자에게 경보를 전송하는 기술로써, 사고를 사전에 예방하고 사고가 발생한 경우에는 신속하게 대응하여 피해를 줄일 수 있게 해준다. 본고에서는 지능형 영상분석 기술이 탐지할 수 있는 이상 행위, 즉 이벤트를 그 목적에 따라서 보안, 비즈니스 인텔리전스, 객체인식으로 구분하여 현재 기술 수준을 살펴볼 것이다. 그리고 앞으로 지능형 영상분석에서 이벤트 탐지 기술의 발전 방향을 사람의 행동인식, 행위 기반 이상 현상 탐지, 군중 환경에서 이벤트 탐지, 지능형 영상분석 구조의 변화 등의 관점으로 구분하여 살펴보고자 한다.
