  abstract= "The visual detection and tracking of moving targets is
     computationally intensive and any but the most simple tasks
     are beyond the ability of single processor architectures.
     Many algorithms that are parallel in nature have been
     suggested for the recognition and tracking of moving
     targets. Implementing these algorithms on parallel computer
     systems requires the transcription of a massively parallel
     architecture onto a system with fewer physical processors.
     This, of course, is a much easier transformation than the
     reverse process: distributing a serial algorithm effectively
     over multiple processing elements.This paper describes a
     parallel Transputer implementation of a vision tracking
     system. The system is able to track a designated target by
     the physical movement of the camera. The camera is mounted
     on a pan and tilt unit and its movement and lens are under
     full control of the system. The system is modular in nature
     having been designed in three stages: i) the pre-processing
     of the image and extraction of edge information, ii) the
     control of the focus and gain of the lens, and iii) the
     detection and tracking of moving targets. The system
     operates in real-time (i.e. 25 frames/second)."
