The proposed approach used facial recognition to detect the face in each frame of the video using facial landmarks, followed by supervised learning using deep neural networks to train the machine learning ...
In this paper, we used a non-contact method that only requires face videos recorded using commercially-available webcams. ...
Thus, this paper considers the use of a non-contact based approach where the passive video of the face can be used to estimate the health metrics. ...
