In this paper we present a novel method for computing phasecongruency by automatically selecting the range of scales over which a locally one-dimensional feature exists. Our method is based on the use of local energy computed in a multi-resolution steerable filter framework. We observe the behaviour of phase over scale to determine both the type of the underlying features and the optimal range of scales over which they exist. This additional information can be used to provide a more complete
