We invite competition proposals for the 12th IAPR International Conference on Biometrics (ICB 2019), in Crete, Greece. The main goal of the competitions is to benchmark state-of-the art algorithms, to consolidate research and identify open biometrics-related problems. We solicit competition proposals on any topic of interest to the broader biometric community and strongly encourage proposals focusing on new emerging fields and open research questions that are able to attract a significant number of participants. Competition organizers having a strong track record in the field are especially welcome. For details, please see the PDF.
