EDGE LINKING BY RIDGE TRACING

Abstract

A multi-phase ridge tracing algorithm for edge liinking si proposed in this study. The main ideal behind our method is that edge gradient maps are regareded as continuous nountain ranges in three-dimensional view. For each tracing phase, we start out with somewhat candidate edge points confined by the first threshold T1 and local maximum. Then the second threshold T2 is acquired to terminate linking. Moreover, to distinguish low gradient magnitude edge and noise or background, multiple precesses are applied and the experimental results exhibit that our effort successfully traces edge points in edge gradient maps.
