Abstract

A theoretical and experimental analysis related to the effect of noise
in the task of vertex identication in unknown shapes is presented. Shapes are
seen as real functions of their closed boundary. An alternative global per-
spective of curvature is examined providing insight into the process of noise-
enabled vertex localization. The analysis reveals that noise facilitates in the
localization of certain vertices. The concept of noising is thus considered and a
relevant global method for localizing Global Vertices is investigated in relation
to local methods under the presence of increasing noise. Theoretical analysis
reveals that induced noise can indeed help localizing certain vertices if com-
bined with global descriptors. Experiments with noise and a comparison to
localized methods validate the theoretical results.
