Facial ageing model considering sun exposure effects
Résumé
Very few things in life are as certain as ageing. Although it is a definite and imminent process, it is neither uniform nor linear, and its pattern varies in different individuals. The pattern of facial ageing in each individual is linked with several intrinsic and extrinsic factors that may change the ageing pattern. Since sun exposure can be referred as the most important environmental factor influencing the facial ageing, having visual representation of its irreparable effects on the face appearance can push tan seeking people to stop extensive exposures to the sun. Unlike numerous studies dealing with the natural ageing process, in this work, we propose a behavioural facial ageing model aiming at presenting the harmful effects of sun exposure on an individual's apparent age. First, a predictive ageing model has been made according to the natural aging process. Then, based on a statistical study one coefficient is obtained that shows the difference in the apparent age of sun phobic and sun seeking people. The final model will be built on the basis of these two, which shows that sun seeking people look older than their natural age.
