The Scale Structure of the Gradient Magnitude

TR-2003-29, Author: Ole Fogh Olsen

March 2003

Abstract

This paper will describe the multi-scale structure of the singularities in gradient magnitude images including data structures for representation and algorithms for extraction. Especially the case of the minima of the gradient magnittude is considered as they constitute a dual representation of the gradient magnitude watersheds proven efficient for multi dimensional image segmentation.
