%X It is believed from psychophysical experiments that human
   vision operates in two stages: a parallel preattentive stage
   which extracts simple visual features and a sequential
   attentive stage in which local features of the scene are
   analysed. A processing model of the early preattentive stage
   has been developed. This model is computationly intensive
   making it unsuitable for implementation on sequential
   computer architectures. The development of a real\-time
   parallel transputer vision system based on this processing
   model is explained.The current implementation performs edge
   filtering over four separate resolution/field\-of\-view
   levels from 256 by 256 monochrome images. Eight T800\-20
   transputers deliver over 40 frames per second. The software
   — hardware architecture is scalable so as to support
   higher resolutions and additional features (such as
   auto\-focusing, movement detection, and tracking) through
   the addition of extra transputers, whilst maintaining at
   least camera frame rates.
