Abstract

In a recent paper on morphological image segmentation [1], Najman and Schmitt introduce the powerful concept of edge dynamics. In this communication, we show that the method that they propose to compute the edge dynamics gives erroneous results for certain spatial configurations, and we propose a new algorithm which always yields correct edge dynamics.
