process mining includes the automated discovery of petri nets from event logs. these event logs are the starting point for various discovery and analysis techniques of the process.  in this paper process model is developed using colored petri nets (cpns) and the supporting software package cpn tools. the restaurant process model is represented for the analysis using a combination of process min...

The work presented in this paper shows how a simple algebraic manipulation of the RGB colour channels of an artificial vision system can significantly improve the performance of an objectlocating mechanism based on unsupervised clustering. The proposed image processing and clustering mechanism forms the first part of a noveltydetecting robot controller. Experiments with two different connection...
