%X 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).
