ANYONE with a digital camera and a PC can now track where intruders or
saboteurs have been in their home, garden or office, thanks to software
originally developed to improve security at a nuclear lab.
The Change Detection System, developed by Greg Lancaster, James L. Jones and
their colleagues at the Idaho National Engineering and Environmental Laboratory
in Idaho Falls, takes two roughly similar digital pictures and lines them up.
Any differences are immediately apparent as the user clicks back and forth
between them.
Importantly, the pictures need not be taken from precisely the same distance
or perspective each time…
