Abstract
A method of forming a template of an image of an object includes the steps of: detecting occurrences of at least one feature type within the image which meet a respective criterion; for each such occurrence, determining a feature position which is a point within the image at which the occurrence of the feature type is to be considered as being located; and constructing a structural mesh of links between the feature positions. A method is also disclosed of forming a template derived from a plurality of templates formed from respective images of different members of the class of objects and combining the templates to form a generalized template. In particular the templates are combined using a genetic algorithm. The invention provides a method of forming a template from one or more images which does not rely on a priori assumptions about the salient features of the object for which a template is to be obtained.
