place the number of CCTV cameras in the UK at 4.2 million, but how can these images all possibly be watched? Researches in Turkey have an answer
: an eye-gaze tracking system placed on the CCTV operators themselves
which can "then automatically produces a summary of the CCTV video sequences they have missed during their shift".From NewScientist article.
"This increases the reliability of the surveillance system by giving a second chance to the operator."
The system uses webcam-style cameras trained on the irises of the CCTV operators. From this, software works out where the operators are looking as they stare at each monitor - and the areas they have not been paying attention to. From this it creates a video of what they missed, for them and their bosses to watch at the end of their shift.
To make sure the summary can be watched as quickly as possible, Vural and Akgul have developed an algorithm that discards frames that show only the background with no people or moving vehicles in them, to leave only a few key frames for each scene of interest. Vural says the system runs on a standard PC and processes the images in real time, so the summary frames are ready to browse, like a fast-motion flip book, at the end of the shift.
