Abstract

Function-Described Graphs (FDGs) have been introduced as a representation of an ensemble of Attributed Graphs (AGs) for structural pattern recognition and a distance measure using restrictions between AGs and FDGs has been reported. Nevertheless, in real applications, AGs can be distorted by some external noise, and therefore some constraints have to be relaxed. To gain more flexibility and robustness, some local costs may be added to the global cost of the labelling depending on the fulfilment of the graph element constraints of the FDG instead of applying hard binary constraints.

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
