Patent Images
1. A face recognition method using physiognomic feature information, comprising:
- defining standard physiognomic types for respective facial elements;
capturing a facial image of a user;
performing basic face recognition using global features of a face in the facial image and detecting locations of the facial elements;
detecting information about the facial elements from the facial image;
normalizing a size of a face area in the facial image based on the facial elements;
calculating similarity scores relative to the standard physiognomic types for the respective facial elements of the user based on the facial elements;
assigning weights to the similarity scores and to results of the basic face recognition, respectively; and
determining similarities to facial data registered in advance in a face database (DB) based on the weighted similarity scores and the weighted results of the basic face recognition.
