ImageNetDiff: Finding Differences in Models

In this paper we propose a method and present a tool as plugin for R ENEW that supports the process of discovery of differences in possibly conflicting versions of all kinds of supported diagrams. These diagrams can be either semiformal UML diagrams, Petri net models or simple JHotDraw drawings. Instead of searching for differences on the syntactical or even on the semantical level, we choose to find differences on the visual level.
