A study of face authentication methods using thermal images
Yuta Watanabe, Yoshitsugu Manabe, Noriko Yata · 2023
Biometrics has been introduced in many facilities, and face authentication is one of the authentication methods that has attracted attention. However, face authentication is influenced easily by changes in lighting conditions. This study proposes a face authentication method using only a thermal camera, which is robust to lighting changes. The proposed method applies FaceNet[1], an authentication method for visible light images, to each of the four parts of the face (face, eyes, nose, and mouth) and tries to improve the accuracy by using a majority voting method.
