Soft-Biometrics Estimation In the Era of Facial Masks
Abstract
We analyze the use of images from face parts to estimate soft-biometrics indicators. Partial
face occlusion is common in unconstrained scenarios, and it has become mainstream during the
COVID-19 pandemic due to the use of masks. Here, we apply existing pre-trained CNN architectures,
proposed in the context of the ImageNet Large Scale Visual Recognition Challenge, to the
tasks of gender, age, and ethnicity estimation. Experiments are done with 12007 images from the
Labeled Faces in the Wild (LFW) database. We show that such off-the-shelf features can effectively
estimate soft-biometrics indicators using only the ocular region. For completeness, we also evaluate
images showing only the mouth region. In overall terms, the network providing the best accuracy
only suffers accuracy drops of 2-4% when using the ocular region, in comparison to using the entire
face. Our approach is also shown to outperform in several tasks two commercial off-the-shelf
systems (COTS) that employ the whole face, even if we only use the eye or mouth regions.
