Closed Circuit Television (CCTV) operators are responsible for maintaining security in various applied settings. However, research has largely ignored human factors that may contribute to CCTV operator error. One important source of error is inattentional blindness--the failure to detect unexpected but clearly visible stimuli when attending to a scene. We compared inattentional blindness rates ...

Due to the population increase all over the world current road infrastructures are unable to keep up with the escalating transportation demands. This situation where travel demands exceeds the capacity of the transportation network is known as traffic congestion. However, it is impractical to build more roads and infrastructure to accommodate these demands. Governments are increasingly recogniz...

Vandalism is a type of the so-called low intensity crimes. However, the nuisance and damage caused by it could cost dearly to the public to clean up. It is also technically difficult in the past to detect and prosecute such a crime, for example, graffiti making. This paper presents an automatic and live graffiti detection system using CCTV cameras and innovative vision algorithms. After a brief...

We present a content-based retrieval method for long surveillance videos in wide-area (Airborne) and near-field (CCTV) imagery. Our goal is to retrieve video segments, with a focus on detecting objects moving on routes, that match user-defined events of interest. The sheer size and remote locations where surveillance videos are acquired necessitates highly compressed representations that are al...

In response to a series of highly unethical incidents in operating rooms South Korea, social consensus has emerged on the need for surveillance medical operations. This turn motivated lawmakers amend Medical Service Act require hospitals and clinics install CCTV cameras their rooms. While rationale this legislation is clear, there are also concerns that law infringes certain rights freedoms pra...

This research uses a task disengagement framework to examine how CCTV surveillance operators and novices respond to the vigilance demands of the detection process. Vigilance tasks are acknowledged as being high in mental workload, yet little is known about how operators deal with these demands in jobs where successful performance is reliant upon sustaining attention on a daily basis. Much vigil...

This paper reports on a variant of the rapid serial visual presentation (RSVP) technique for low vision reading called elicited sequential presentation (ESP). In both techniques, words are presented sequentially at a constant screen location, but with ESP, the reader elicits presentation of each new word by means of a button press, rather than (as with RSVP) being presented with it automaticall...
