Frontal face landmark displacement across age

Human face contain fiducial landmarks that are located at some distance from each other. Facial shape change due to craniofacial development making landmarks to gradually drift from each other to occupy space created on the cranium. This study investigate displacement of fiducial landmarks from each other across age. Regression analysis was performed on Euclidean distances between landmarks to determine general trend of landmark displacement across age. Results show that, mouth is significantly displaced from the eyes as compared to displacement of nose from eyes and displacement between eyes. It is also observed that the mouth is slightly displaced from the nose and forehead.
