Passive Video Surveillance for Security Applications
Peter Nicol
Abstract:
This project incorporates a security system, which would require no
human input to detect any suspicious movements in a sequence of images
(ie. Video Stream). The idea was to integrate a software system in conjunction
with the employment of security personnel to monitor video streams from
cameras and then respond appropriately to suspicious situations. Using
Matlab version 5.3 ® in the Microsoft Windows 98 ® environment,
the project makes use of the Video for windows interface, making it compatible
with most framegrabbers and USB cameras. A detailed discussion of the operation
of the security system follows. The software makes use of image subtraction
to successfully detect a motion and then matches the object to known set
images subsequently making a decision on the result of the matching of
the images. The software runs at a fast enough rate to be able to display
at frame-rate of 3 to 4 frames per second, which is acceptable for the
conditions it would be running under.
