<title>Delineation And Feature Extraction</title>

Abstract

Image analysis is a problem in data reduction. The only practical approach is to adopt a strategy where the reduction is effected in several stages. Structural analysis is probably the most useful method although difficult to implement properly. The crucial phase in which objects are delineated is the most problematic. Hardware to perform automatic image analysis can utilise structural analysis but to avoid undesirable restrictions a completely programmable system is required. The MAGISCAN is a high performance software based image analysis system for which high level problem solving languages have been developed.
