  • Face authentication method and device
    Patent number: 9898649
    Abstract: The disclosure discloses a face authentication method and device. The face authentication method includes: acquiring multiple face training images; extracting Gabor features of the multiple face training images; extracting Pattern of Oriented Edge Magnitude (POEM) features of the multiple face training images; fusing the Gabor features of the multiple face training image and the POEM features of the multiple face training image to acquire positive samples and negative samples of the multiple face training images; training the positive samples and negative samples of the multiple face training images to obtain training results by an AdaBoost algorithm; and performing face authentication by the training results.
    Type: Grant
    Filed: October 17, 2014
    Date of Patent: February 20, 2018
    Assignee: BEIJING TECHSHINO TECHNOLOGY CO., LTD.
    Inventors: Ning Wang, Xiangde Zhang, Wuming Jiang, Yaoluo Zhang
  • Eye location method and device
    Patent number: 9842247
    Abstract: An eye location method and device includes: receiving a face image; locating a position of a nose and positions of eyes in the face image; determining a facial symmetry axis according to the position of the nose; and regulating the positions of the eyes by the facial symmetry axis to obtain target positions of the eyes. By the method and the device, the problem of poorer eye location accuracy in the conventional art is solved, and the effect of improving eye location accuracy is further achieved.
