Abstract
A three-dimensional (3D) image-based facial verification method and apparatus is provided. The facial verification method may include capturing a facial image of a 3D face of a user, determining an occluded region in the captured facial image by comparing the captured facial image and an average facial image, generating a synthetic image by synthesizing the captured facial image and the average facial image based on the occluded region, and verifying the user based on the synthetic image.
Claims20
A mobile verification apparatus comprising:
- a camera configured to capture a three-dimensional (3D) image;
- a processor configured to:
- obtain a facial image including a 3D face of a user based on the 3D image,
- determine an occluded region in the facial image by comparing the facial image and a target facial image,
- determine a reliability of the facial image based on the occluded region in the facial image, and
- verify the user based on the determined reliability of the facial image,
- wherein the processor is further configured to:
- extract features from the facial image to perform a facial verification using a landmark detection based on a neural network model, and
- terminate the verifying using the facial image without extracting features from the facial image based on the reliability of the facial image.
An electronic apparatus comprising:
- a processor configured to:
- obtain a facial image including a 3D face of a user;
- determine an occluded region in the facial image by comparing the facial image and a target facial image;
- determine a reliability of the facial image based on the occluded region in the facial image;
- and
- verify the user based on the determined reliability of the facial image,
- wherein the processor is further configured to:
- extract features from the facial image to perform a facial verification using a landmark detection based on a neural network model;
- and
- terminate the verifying using the facial image without extracting features from the facial image based on the reliability of the facial image.
