Query: Masked Face Recognition Challenge: The WebFace260M Track Report   According to WHO statistics, there are more than 204,617,027 confirmed
COVID-19 cases including 4,323,247 deaths worldwide till August 12, 2021.
During the coronavirus epidemic, almost everyone wears a facial mask.
Traditionally, face recognition approaches process mostly non-occluded faces,
which include primary facial features such as the eyes, nose, and mouth.
Removing the mask for authentication in airports or laboratories will increase
the risk of virus infection, posing a huge challenge to current face
recognition systems. Due to the sudden outbreak of the epidemic, there are yet
no publicly available real-world masked face recognition (MFR) benchmark. To
cope with the above-mentioned issue, we organize the Face Bio-metrics under
COVID Workshop and Masked Face Recognition Challenge in ICCV 2021. Enabled by
the ultra-large-scale WebFace260M benchmark and the Face Recognition Under
Inference Time conStraint (FRUITS) protocol, this challenge (WebFace260M Track)
aims to push the frontiers of practical MFR. Since public evaluation sets are
mostly saturated or contain noise, a new test set is gathered consisting of
elaborated 2,478 celebrities and 60,926 faces. Meanwhile, we collect the
world-largest real-world masked test set. In the first phase of WebFace260M
Track, 69 teams (total 833 solutions) participate in the challenge and 49 teams
exceed the performance of our baseline. There are second phase of the challenge
till October 1, 2021 and on-going leaderboard. We will actively update this
report in the future.
