Embodiment Construction

[0058] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

Abstract

The embodiments of the invention provide a face image processing method and apparatus. The method comprises the following steps: obtaining a plane external rotation angle value of a face from the posture parameters of a face image; determining whether one side from the left side and the right side of the face is incomplete; if the incomplete side exits, according to the angle value, determining the incomplete side, and covering the incomplete side with the other side of the face after mirror imaging is performed on the other side of the face. For the face image corrected through 3D correction, through such means as determining the plane external rotation angle value in the posture parameters of the face image and the like, whether one side from the left side and the right side of the face is incomplete can be known, and then the incomplete side is covered by the other side of the face after the mirror imaging is performed on the other side of the face. According to the invention, by use of the left-right symmetry characteristic of the face, the incomplete side is compensated by use of the other side in a mirror image mode, such that problem of the incompletion existing in some areas of the face after the 3D face correction is solved, and the face identification success rate is improved.

Description

technical field [0001] The present disclosure relates to the technical field of face image recognition, and in particular to a face image processing method and device. Background technique [0002] For the face in the image, according to the pose of the face, it can be divided into a frontal face and a pose face. A frontal face means that the face is facing the camera, while a pose face means that the face is in a certain posture and is not facing the camera (for example, the face is facing the camera sideways). Face image recognition technology is usually only used for the recognition of frontal faces, but cannot be used for the recognition of pose faces. In the related art, 3D correction can be performed on the pose face, converted into a frontal face, and then face recognition is performed, so as to improve the adaptability of the face image recognition technology. [0003] However, in the process of implementing the disclosed solution, the inventor found that after per...
