Patent number: 11721131Abstract: A liveness test method and apparatus is disclosed. The liveness test method includes detecting a face region in an input image for a test target, implementing a first liveness test to determine a first liveness value based on a first image corresponding to the detected face region, implementing a second liveness test to determine a second liveness value based on a second image corresponding to a partial face region of the detected face region, implementing a third liveness test to determine a third liveness value based on an entirety of the input image or a full region of the input image that includes the detected face region and a region beyond the detected face region, and determining a result of the liveness test based on the first liveness value, the second liveness value, and the third liveness value.Type: GrantFiled: September 8, 2021Date of Patent: August 8, 2023Assignee: Samsung Electronics Co., Ltd.Inventors: Byungin Yoo, Jingtao Xu, Chao Zhang, Hao Feng, Yanhu Shan, Youngjun Kwak, Youngsung Kim, Wonsuk Chang, Jaejoon Han
