Humans in the Loop is publishing an open access dataset annotated as a contribution to the worldwide fight against COVID-19. 

The dataset consists of 6k images acquired from the public domain with an extreme attention to diversity, featuring people of all ethnicities, ages, and regions.

In addition, the datset covers 20 classes of different accessories as well as a classification of faces with a mask, without a mask, or with an incorrectly worn mask.

The images were collected and annotated by the refugee workforce of Humans in the Loop in Bulgaria.
