Method for aligning the face of a person in an image

Abstract

Method (700), implemented by a data-processing device (202), for aligning a face (103a, 301) of an individual (103) in an image (I700), the method (700) comprising the following steps: (a) detecting (701), in an image (I700) of the face (103a, 301) of an individual (103), the positions of a left eye (503), of a right eye (504), of a midpoint (505) between the right eye (504) and left eye (503), and of a midpoint (506) of the mouth (501); (b) applying (702) a first geometric transformation (TG1) so that the positions of the midpoint (505) between the left eye (503) and right eye (504) and of the midpoint (506) of the mouth (501) coincide with reference points (801, 802); (c) applying (703) a second geometric transformation (TG2) so that the position of the closest eye (503, 504) in the depth of the image (I700) coincides with the position of a vertical reference line (901, 902).
