Abstract

We propose a system that can detect empty mugs to monitor customers in pubs and restaurants. The evaluation results revealed that our proposed system has significantly high precision and good recall, even for very small and tilted mugs in images captured using wide-angle ceiling cameras, and also has a practical detecting speed.
