   Face Anti-spoofing, Face Presentation Attack Detection

   Yaojie Liu, Joel Stehouwer, Amin Jourabloo, Yousef Atoum, Xiaoming Liu

   Biometrics utilize physiological, such as fingerprint, face, and iris, or behavioral characteristics, such as typing rhythm and gait, to uniquely identify or authenticate an individual. As biometric systems are widely used in real-world applications including mobile phone authentication and access control, biometric spoof, or Presentation Attack (PA) are becoming a ...

   Generic Object Sensor and Spoof Noise Classification, Modeling, and Synthesis

   Joel Stehouwer, Amin Jourabloo, Yaojie Liu, Xiaoming Liu

   Biometric recognition is increasingly used in commercial and high-security settings. Because of this, the threat of spoofing techniques, the act of presenting a fake biometric object to a sensor, is a large concern. Recent research has focused on face, fingerprint, and iris anti-spoofing. However, no other research attempts to use ...

   Pose-Invariant Face Alignment (PIFA)

   Amin Jourabloo, Yaojie Liu, Xiaoming Liu

   Face alignment is a process of applying a supervised learned model to a face image and estimating the locations of a set of facial landmarks, such as eye corners, mouth corners, etc. Face alignment is a key module in the pipeline of most facial analysis algorithms, normally after face detection ...

   Attribute Preserved Face De-identification (APFD)

   Amin Jourabloo, Xi Yin, Xiaoming Liu

   The human is the dominant object of interest in the huge network of surveillance cameras deployed in buildings, airports, streets, and so on. The captured images and videos enable various applications such as face recognition, person re-identification, crowd and behavior analysis, etc. Certain applications, such as face recognition, rely on ...
