There is not 100% accuracy on masked face recognition. Algorithms like the viola-jones face detection algorithm can detect masked human faces from the digital images. I applied the viola jones algorithm on MASKED human face images and it successfully detects human masked faces.

The face detection system can extract the different facial features from a digital image. A set of facial features extracted from a digital image includes eyes, nose, mouth, and face region. Face recognition is a difficult task due to the different facial expressions. With the help of a face detection system presence of a human face can be detected easily. For the detection of different facial features, the Viola-Jones algorithm is used in the proposed work. To make the task more manageable, Viola-Jones requires full view frontal upright faces.

First, learn about FACE DETECTION.  Then face recognition would be an easy task for you. Because most of the computer algorithms work first on face detection after that they can recognize. First learn, how to detect humans or anything you want to detect (objects/ birds/other). When your software will be able to detect it. Then train it for recognition. I worked on Human face recognition. First, I created software for human face detection. Once your software can detect it. You can easily train it for recognition/identification.

There are already several efforts in place to leverage artificial intelligence in the fight against coronavirus. Some of these methods include automatically measuring people’s temperature in public places, diagnosing COVID-19 infections from chest x-ray scans, and using machine learning algorithms to predict the spread of the virus. 1.)
