Abstract
Disclosed herein are methods, apparatus, and systems for face biometric recognition. A biometric recognition device includes at least one non-visible illuminator, at least one image capture device, and a processor. The at least one image capture device and the at least one non-visible illuminator are in a differential measurement configuration. The processor determines one or more eyes and a face from one or more captured images, performs liveness detection by comparing one or more pupil images from even-odd image pairs from the one or more captured images, wherein a non-noise color or brightness difference indicates pupil liveness, performs face encoding on the live face to generate face template, performs face matching on the face template to generate a face result, and uses one or more of the liveness result and the face result to enable the user to access an object.
