- Abstract summary: In this article, we analyze 2.04 million social media images for six US cities.
An increase in masks worn in images is seen as the COVID-19 cases rose, particularly when their respective states imposed strict regulations.
mask compliance in the Black Lives Matter protest was analyzed, eliciting that 40% of the people in group photos wore masks.

- Abstract: Wearing masks is a useful protection method against COVID-19, which has
caused widespread economic and social impact worldwide. Across the globe,
governments have put mandates for the use of face masks, which have received
both positive and negative reaction. Online social media provides an exciting
platform to study the use of masks and analyze underlying mask-wearing
patterns. In this article, we analyze 2.04 million social media images for six
US cities. An increase in masks worn in images is seen as the COVID-19 cases
rose, particularly when their respective states imposed strict regulations. We
also found a decrease in the posting of group pictures as stay-at-home laws
were put into place. Furthermore, mask compliance in the Black Lives Matter
protest was analyzed, eliciting that 40% of the people in group photos wore
masks, and 45% of them wore the masks with a fit score of greater than 80%. We
introduce two new datasets, VAriety MAsks - Classification (VAMA-C) and VAriety
MAsks - Segmentation (VAMA-S), for mask detection and mask fit analysis tasks,
respectively. For the analysis, we create two frameworks, face mask detector
(for classifying masked and unmasked faces) and mask fit analyzer (a semantic
segmentation based model to calculate a mask-fit score). The face mask detector
achieved a classification accuracy of 98%, and the semantic segmentation model
for the mask fit analyzer achieved an Intersection Over Union (IOU) score of
98%. We conclude that such a framework can be used to evaluate the
effectiveness of such public health strategies using social media platforms in
times of pandemic.

We propose a method for enhancing data sets containing faces without masks by creating synthetic masks and overlaying them on faces in the original images.
We employ our method to generate a number of 445,446 (90%) samples of masks for the CASIA-WebFace data set and 196,254 (96.8%) masks for the CelebA data set.
We show that our method produces significantly more realistic training examples of masks overlaid on faces by asking volunteers to qualitatively compare it to other methods or data sets.

Wearing a mask is a strong protection against the COVID-19 pandemic, even though the vaccine has been successfully developed and is widely available.
This observation prompts us to devise an automated approach to monitor the condition of people wearing masks.
Unlike previous studies, our work goes beyond mask detection; it focuses on generating a personalized demonstration on proper mask-wearing.
