EDGE AND RIDGE IDENTIFICATION

摘要

A method of identifying characteristic lines (904) or line segments in an image. The method includes selecting a point (908) in the image, providing a plurality of sets of data representations of a vicinity of the selected point and weights to be used with the data representation, generating, for each set of data and weights, a brightness function representing the vicinity of the point responsive the data and weights of the set, choosing a course of analysis of the vicinity of the selected point according to the chosen course of analysis, so as to determine whether the portion includes a characteristic line or to determine the geometrical parameters of the characteristic line.
