Fast camera calibration for the analysis of sport sequences
Semantic analysis of sport sequences requires camera calibration to obtain player and ball positions in real-world coordinates. For court sports like tennis, the marker lines on t...

Towards an Implicit Characterization of NCk
We define a hierarchy of term systems Tk by means of restrictions of the recursion schema. We essentially use a pointer technique together with tiering. We prove Tk NCk Tk+1 , for ...

Excluding induced subgraphs: Critical graphs
Determining the cardinality and describing the structure of H-free graphs is wellinvestigated for many graphs H. In the nineties, Prömel and Steger proved that for a graph H with...
