This volume provides the reader with a "snapshot" of state-of-the-art developments in computer vision and image processing that have taken place in the UK during 1990 and 1991. At this year's British Machine Vision Conference (BMVC '91) - the premier annual conference for the UK vision community - competition for papers to be accepted was as keen as in past years and the quality of those that were selected illustrates the high standards of research and development in this strategically important area. These papers, along with the shorter posters, cover topics such as segmentation and feature extraction, stereo and motion analysis, shading and texture methods, object recognition and inspection techniques, and medical image processing, as well as a variety of new developments in computer hardware, including active sensing. This book is an important reference for researchers and applications workers in computer vision, machine vision, and image processing, in academic institutions and industry - in fact for anyone wanting to keep up to date in this challenging and fast-moving area.

Lewis Carroll once wrote a story about a king who wanted a very accurate map of his kingdom. The king had a pathologically fastidious eye for detail and consequently decided that the map was to be produced at a scale of 1:1. The scribes dutifully set to and, in time, the map was made. The map carried details of every tree, every rock and every blade of grass throughout the entire land. The problem occurred when they tried to use -it. First of all, the map was extraordinarily difficult to open out and line up with the countryside. Its sheer bulk meant that it took whole armies to carry it and a great host of bureaucrats and technicians to maintain the information. Such was the detail of the map that as soon as the wind blew strongly, whole sections needed to be redrawn. What was worse was that all the farmers protested because the map completely cut out the light from the sun and all the crops died. Eventually the howls of protest became so strong that the king was forced to take action. He did away with the old paper copy and decided to use the kingdom itself as the map. All lived happily ever after. There are, at least, two morals to this tale. First, you are almost certainly doomed to failure if you do not get the representation of the problem right.
