Summary: | Techniques for liveness detection using progressive eyelid tracking are disclosed. A series of frames of a user are captured by a camera. The user's face, including a pair of eyes and eyelids, are detected within each of a plurality of captured frames. A respective pair of regions of interest is extracted from each captured frame within the plurality of respective captured frames, each respective region of interest including a respective eye of the respective pair of eyes detected and a respective eyelid corresponding to the respective eye. A respective score corresponding to a percentage of the respective eye unobstructed by the respective eyelid is calculated for each region of interest. A liveness indication is generated by a pattern recognizer analyzing the series of respective pairs of scores for an abnormal eyelid movement sequence. |
