AB  - Human life is bound to limits of time. Ageing is an inevitable process conditioned in linearity of time.
Face is the mirror of this ageing process. The tools of image enhancement play a significant role through
effective filtering techniques. So far, no researchers can find a method to develop image enhancement from
difference equations. This research study illustrates a specific technique to remove speckle noise in any digital
image using the solutions of difference equations. Here we propose a novel model to remove ageing marks from
the face images. We bring out a series of mask from the oscillatory solution of a certain third order difference
equation. This, for specific values, helps us to remove noise in a different way. Illustrations through common
face outlook and ageing are considered.
