Closed circuit television systems (CCTV) are becoming more and more popular and are being deployed in many offices, housing estates and in most public spaces. Monitoring systems have been implemented in many European and American cities. This makes for an enormous load for the CCTV operators, as the number of camera views a single operator can monitor is limited by human factors. In this paper,...
In this paper, we survey the state-of-the-art in the development of automated visual surveillance systems and discuss on how this can be applied for the national security. Video surveillance system is the very complex task that needs to combine multiple technologies together. We summarize the progress of this technology in term of sensor and devices, infrastructure, and intelligent technologies...
The majority of work described in this paper was conducted as part of the Recovering Evidence from Video by fusing Video Evidence Thesaurus and Video MetaData (REVEAL) project, sponsored by the UK’s Engineering and Physical Sciences Research Council (EPSRC). REVEAL is concerned with reducing the time-consuming, yet essential, tasks undertaken by UK Police Officers when dealing with terascale co...
The effectiveness of CCTV surveillance networks is in part determined by their ability to perceive possible threats. Our traditional means for determining a level of threat has been to manually observe a situation through the network and take action as appropriate. The increasing scale of such surveillance networks has however made such an approach untenable, leading us look for a means by whic...
The principle of the optical section has been used to develop a profiling attachment for CCTV pipe inspection cameras. A light source, placed in front of the camera, projects a ring of light onto the pipe wall, which is then viewed by the camera. Any distortion in the pipe wall will be made visible by the light ring. The CCTV image is digitized by an electronic frame grabber and the light ring ...
In recent years, single object tracking has been extensively studied and achieved much development. However, multiple objects tracking is still an issue that remains to be addressed. Generally speaking, existing multiple objects tracking methods employ a manner of simultaneously tracking each object respectively. In this paper, we develop a multiple ship tracking algorithm based on deformable p...

Previous investigations in remote visual inspection and dosed circuit television viewing of cannon bores revealed advantages over standard manual bore inspection techniques. Recent developements in industrial quality solid state CCTV systems present advantages over the older CCTV systems. Some disadvantages of the older systems are pointed out and suggestions for a new system to alleviate these...
