references, although there appear to be so many available that I have certainly not surveyed them
all. Again I apologise for all omissions in my reference citations.

It has been found, in our studies on
human visual threshold performance, that a number of aspects
of display imagery - particularly the image quality, display noise and discrete sampling - have
marked effects on performance. Considerable space is therefore given over to assessment of such
display characteristics, when applied to
computer vision (Chapters 6, 7, and 8).

Much of the text and illustrations to be presented are based heavily on a large number of British
Aerospace Reports prepared over the past 12 years. These reports have covered the growing
development of our computer vision work, together with specialist studies into particular facets of the
overall subject. In preparing the book, I have endeavoured to include sufficient details and
illustrations such that the reader will not need, in general, to seek to refer to these source reports.
Nevertheless, for completeness, I
have included, at the end, a short bibliography of various open
publications which have appeared from time to time, covering both the computer vision studies and
the earlier human visual performance and image evaluation studies.
Because the computer vision
studies have been in progress for several years, some aspects of the subject reported are already
several years old, whilst other aspects are of very recent origin. This reflects what the author hopes

is a self-coherent, progressive and unfolding story of a computer vision concept.

2.1. INTRODUCTION

It has to be admitted that the human visual system is capable of carrying out a wide variety of image
analysis and interpretation tasks with what appears to be utmost ease. Many visual tasks which one
