전 세계적으로 9.11로 대표되는 자살테러, 비행기테러, 화학가스 테러 등에 의한 인명피해가 늘고 있다. 1986년 김포공항 폭발사고, 1995년 음진리교 지하철 사린가스 사건, 2001년 9.11 사건, 2003년 필리핀 공항 폭탄테러 사건 등의 큰 테러 외에도 작은 사건은 무수히 많다. 이러한 테러 사태를 미연에 방지하기 위한 지능형 영상 보안 감시 시스템이 사회적으로 연구되어왔고 도입되어 왔다. 기존의 지능형 영상 보안 시스템은 모션 디렉션 기반으로 금지구역의 침입자로 판단되는 사람을 찾는 기능 중심으로 발전해왔다. 또한 보안요원의 관찰 모니터를 통해 화면을 계속 주시하는 한계 시간의 존재와 모니터 증가에 따른 한계 시간은 더 급감하게 되는 것으로 판단되었다. 이에 본 연구를 통해 유기물 탐지의 자동화를 추구하고, 보안 요원의 감시 업무를 도와 국가 주요 시설물의 유기물 자동 탐지를 통해 테러로부터 안전하게 보호하고자 한다.

Video surveillance is consists of cameras, transmission devices, storage and playback devices, and is used for crime prevention and disaster monitoring. Recently, it has been spreading to a wide variety of fields, and has developed into an intelligent video surveillance system that can automatically recognize or track characteristic objects of people and things. The purpose of this study was to investigate the cases of video surveillance service applying the latest technology by dividing it into the home, public, and private sectors. also this study tried to investigate and research what advantage it brings from a business perspective. By looking at the cases introduced in this study, it was confirmed that the viedo security service is developing intelligently, such as excellent compatibility with CCTV, multiple video surveillance, CCTV screen motion detection, and alarm through automatic analysis.

최근 감시시스템 구축에서 디지털 비디오 레코더(DVR)를 이용하는 방식이 주를 이루고 있다. 영상압축 기술의 발전에 따라 디지털 비디오 레코더는 H.264/AVC 인코더를 기반으로 저장 공간 대비 고화질의 영상 저장이 가능해졌다. 또한, 다수 채널의 동시 처리가 가능해졌을 뿐만 아니라 영상 압축 및 저장 기능 외에 지능형 감시를 위한 기능이 요구되고 있다. 본 논문에서는 H.264/AVC 압축 비트열에서 움직임 벡터 추출 및 분석을 통한 영상내 이동 물체 검출 방법을 제안한다. 압축 비트열에서 현재 프레임과 이전 프레임의 움직임 벡터들의 크기와 각도를 비교하여 임계값 이하인 움직임 벡터들을 추출하여 이동 물체를 검출하였다. 이동 물체 검출 성능 평가를 위해 H.264/AVC의 참조 프로그램인 JM 15.1을 사용하여 인코딩 및 비트열 분석을 수행 하였고, 움직임이 검출된 시간 구간만을 디코딩 후 저장하는 알고리즘을 구현하였다. 제안된 방식은 디코딩 부분의 연산량 감소뿐만 아니라 저장소의 물리적 공간 절약이 가능하다.

Under the obligations which is a protection of privacy and a respect for human rights of each person critical is caused by time about surveillance system and CCTV markets which stagnate during that about 911 terror after that securities about importance raising and direction of a ceremony crime prevention are caused by with world grafting of up-to-date IT technique of domestic and changes with the intelligent style surveillance system which leads and quite from the remote place the dead zone this the image which is photographed the Internet leads and with the intelligent style CCTV surveillance systems will be able to control which area at real-time watch and is embodied.

These days there are many researches on the vision based technology using deep learning. The lots of studies on the intelligent operation and maintenance for railway station system used technologies with vision analysis function. This paper analyzes the papers which studied the intelligent station system with vision analysis function for passengers and facilities monitoring, platform monitoring, fire monitoring, and effective operation and design. Also, this paper proposes research which uses the more powerful vision technology with deep-learning for smart railway station system.

In this paper we proposed an algorithm selection method based on the features of video inputs which are acquired from the large scale integrated surveillance system. The example of integrated surveillance system is the metro railway system. Automated surveillance system at large area saves the human resource and minimizes the non-observing spots. We have analyzed the input video under this system in order to apply adequate video analytics algorithms in each installing places and for each situation. Based on the analysis, we suggested event processing scenarios and video analytic algorithm selection.

Recently lots of problems are emerged on the conventional surveillance systems at several areas. Many research activities have been processing on those problems. Therefore, in this paper, it is helpful to all sorts of accident prevention and safe driving, and risks linked to the outside or the administrator tells, that intelligent video surveillance system which can be real-time analysis and monitoring configuration, technical elements, required features, application and its applies.

When a video surveillance system tracks a specific object, it is very important to get quickly the information of the object through fast image processing. Usually one camera surveillance system for tracking the object made results in various problems such like occlusion, image noise during the tracking process. It makes difficulties on image based moving object tracking. Therefore, to overcome the difficulties the multi video surveillance system which installed several camera within interested area and looking the same object from multi angles of view could be considered as a solution. If multi cameras are used for tracking object, it is capable of making a decision having high accuracy in more wide space. This paper proposes a method of recognizing and tracking a specific object like a car using the homography in which multi cameras are installed at the crossroad.

In this paper, an intelligent security camera over internet is proposed. Among ISC methods, watersheds based methods produce a good performance in segmentation accuracy. But traditional watershed transform has been suffered from over-segmentation due to small local minima included in gradient image that is input to the watershed transform. And a zone face candidates of detection using skin-color model. last step, face to check at face of candidate location using SVM method. It is extract of wavelet transform coefficient to the zone face candidated. Therefore, it is likely that it is applicable to read world problem, such as object tracking, surveillance, and human computer interface application etc.

As the industrial society is developing wars, terrors, and vicious crimes is getting increased. These dangerous factors are caused of casualty and subversiveness of social order. Such vicious crimes lead people to feeling of insecurity. That is why naturally people want to build and inspect strengthened security system. CCTV camera system which can be said as the most popular security system is being installed in public places has large number of floating population. This trend is required to develop the intelligent video security technology and propagate it since the importance of security technology is getting high. This thesis will be described regarding the trend of the intelligent surveillance camera and the scenario.
