Automatic facial point detection plays arguably the most important role as an intermediary step for many subsequent face processing operations that ranges from biometric recognition to the understanding of mental states. Distinguishable characteristic of points on face is known as facial landmarks eg. eye corner, mouth corner etc. Though it is conceptually very simple to locate landmarks, the computer vision problem has proven extremely challenging due to compound factors such as scale, pose, expression, occlusion, illumination and inherent face variability. The purpose of this survey is to give an overview of facial landmarks localization techniques and their progress over last 7-8 years.
