  • Method and apparatus with liveness testing
    Patent number: 11625954
    Abstract: A method with liveness testing may include: acquiring an infrared (IR) image including an object, and a depth image including the object; generating a first preprocessed IR image by performing first edge enhancement preprocessing on the IR image; generating a preprocessed depth image by performing second edge enhancement preprocessing on the depth image; and determining whether the object is a genuine object based on the first preprocessed IR image and the preprocessed depth image.
    Type: Grant
    Filed: January 27, 2022
    Date of Patent: April 11, 2023
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Youngjun Kwak, Byung In Yoo, Yong-Il Lee, Yunhao Zhang, Huxing Sun
