Patent number: 10134177Abstract: A method and an apparatus for adjusting a pose in a face image are provided. The method of adjusting a pose in a face image involves detecting two-dimensional (2D) landmarks from a 2D face image, positioning three-dimensional (3D) landmarks in a 3D face model by determining an initial pose of the 3D face model based on the 2D landmarks, updating the 3D landmarks by iteratively adjusting a pose and a shape of the 3D face model, and adjusting a pose in the 2D face image based on the updated 3D landmarks.Type: GrantFiled: January 15, 2016Date of Patent: November 20, 2018Assignee: Samsung Electronics Co., Ltd.Inventors: Xuetao Feng, Hao Feng, Hongwei Zhang, Lujin Gong, Changkyu Choi, Jae-Joon Han, Sungjoo Suh, Wonjun Hwang, Biao Wang
