Abstract
A method of face anti-spoofing, comprising, receiving a near infra-red facial image, having a near infrared channel, receiving a red-green-blue facial image, having a red channel, a green channel and a blue channel, generating a synthetic three channel image based on the near infrared channel, the red channel, the green channel and the blue channel and training a deep neural network based on the synthetic three channel image.
Claims9
A method of facial recognition, comprising:
- receiving a near infrared facial image, having a near infrared channel;
- receiving a red-green-blue facial image, having a red channel, a green channel and a blue channel;
- generating a synthetic three channel image, based on the near infrared channel, the red channel, the green channel and the blue channel, having a first new channel, a second new channel, and a third new channel;
- and
- processing a deep neural network based on the synthetic three channel image wherein the near infrared facial image and the red-green-blue facial image are fed into the deep neural network.
