Abstract

An embodiment of the invention provides a method for use in face recognition. The method includes: obtaining a coordinate of facial feature points after detection of the facial feature points of a user image; calculating the angular difference between a human face and a horizontal direction based on the coordinate of facial feature points, and rotating the user image until the angular difference between the human face and the horizontal direction matches a preset standard angle; calculating a size ratio between the human face and a preset standard human face according to the coordinate of facial feature points, and scaling the user image according to the size ratio; and according to the location of the facial feature points in the user image, cropping the user image after rotation and scaling into a standard area size so that the facial feature points are in the standard position of the standard area, and obtaining an aligned facial image of a consistent size through pre-processing of the user image so that the facial features of the same user are more consistent and the effects of low-quality images on face recognition are eliminated. In addition, the invention also provides an apparatus for use in face recognition.

Description

technical field [0001] Embodiments of the present invention relate to the field of identification, and more specifically, embodiments of the present invention relate to a method and device used in face recognition. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein may include concepts that could be explored, but not necessarily concepts that have been previously thought of or explored.
