The concept of visual search embraces a wide range of processing activities, from human cognitive phenomana to applied problems for both human and machine vision in industrial, medical and military environments. This book, the second to be derived from the series of internationl conferences on visual search organized under the auspices of the Applied Vision Association, brings together research from a variety of disciplines, enabling the reader to share experiences at the cutting edge, accessing knowledge which might otherwise be locked away in specialist journals or grey literature.
