USER AUTHENTICATION APPARATUS, USER AUTHENTICATION METHOD AND TRAINING METHOD FOR USER AUTHENTICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18355020 titled 'USER AUTHENTICATION APPARATUS, USER AUTHENTICATION METHOD AND TRAINING METHOD FOR USER AUTHENTICATION
Simplified Explanation
- The patent application describes a method and apparatus for user authentication using a frontalized face image. - The method involves acquiring an input image of the user's face and calculating a confidence map with confidence values for authenticating the user. - The confidence map is generated by comparing the input image with a depth image of the user's frontalized face. - A second feature vector is extracted from a second image generated using the input image and the confidence map. - A first feature vector is obtained from an enrolled image of the user. - The user authentication is performed by correlating the first feature vector with the second feature vector.
Original Abstract Submitted
A user authentication method and a user authentication apparatus acquire an input image including a frontalized face of a user, calculate a confidence map including confidence values, for authenticating the user, corresponding to pixels with values maintained in a depth image of the frontalized face of the user among pixels included in the input image, extract a second feature vector from a second image generated based on the input image and the confidence map, acquire a first feature vector corresponding to an enrolled image, and perform authentication of the user based on a correlation between the first feature vector and the second feature vector.
