Some Defects in Finite-Difference Edge Finders

Research output: Contribution to journalArticle

Abstract

This paper illustrates and explains various artifacts in the output of five finite difference edge finders (those of Canny, Boie and Cox, and three variations on that of Marr Hildreth) reimplemented with a common output format and method of noise suppression. These artifacts include gaps in boundaries, spurious boundaries, and deformation of region shape.
