Abstract. Petri nets are widely used for modeling and analyzing workflows. Using the token-game semantics, Petri net-based workflow models can be analyzed before the model is actua...
In this paper, we present the logarithmic total variation (LTV) model for face recognition under varying illumination, including natural lighting conditions, where we rarely know t...
