Visitor face tracking system using OpenCV library

This paper presents the development of visitor face tracking system using OpenCV library. This system can be used for security purpose to record the visitor face. The user can identify who had been visiting him/her when away from the place. Visitors just need to appear in front of the web camera for at least 10 second, their image will be recorded. The system provides several functions such as activation of objects detection by user and retrieves the visitor's data. User can print out, delete or save the visitor image. The system had been tested in the real application environment.
