Definition

Face alignment refers to transforming a given face image to a canonical coordinate system. This is done by automatically detecting facial fiducial points also called facial landmarks or keypoints and then using standard transformation methods such as affine/similarity transformation. These fiducial points are predefined points on the face image which are mainly located or centered around facial parts such as the eyes, nose, chin, and mouth corners as shown in Fig. 1.

Sample results for facial landmark localization task. First image shows the landmarks when all the facial components are visible. (Image taken from iBug dataset [1]). Second image taken from COFW dataset [2] shows the landmarks when face parts are invisible due to occlusion. Third image from AFW dataset [3] shows typical keypoints used for face alignment after localization. All results generated using Kumar et al. [4]
