Abstract

This paper discusses the poor performance of the Canny edge detector at junctions formed by three edges, where connectivity is usually destroyed in an arbitrary way. This problem is shown to be due to the non-maximal suppression algorithm, used to identify points of inflection in the grey-level surface. A method to overcome the problem, based on local evidence in the gradient vector, is reported and demonstrated.
