An automatic computer authentication method for photographic faces and living faces

The invention discloses a computer automatic identification method of photo face and live face, which comprises the following steps: (1) performing face detection and eye location; (2) capturing an eye area; (3) calculating an opening-closing level of the eyes in a normalized image; (4) establishing a model for judging wink actions through applying conditional random field theory; (5) processing each frame image in an unidentified video as per steps (1) to (3), and judging whether the wink action exists in the unidentified video through applying the model and the reasoning method of the conditional random field theory in the step (4), thereby completing the automatic identification of the photo face and the live face. The invention realizes the computer automatic identification of the photo face and the live face with a single camera head.
