  abstract= "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."
