Aesthetic surgery induced transformation face insensitive features: The medical and theoretical standpoint

Abstract

The changes in facial appearance resulting from the effect of plastic surgery may manifest in the form of textural variations, and/or geometric variations with respect to the facial structural features such as eyes, nose, mouth, jaw, nose, brow, etc. This study argues that despite these variations, there exist facial features that are insensitive to the effect of plastic surgery. This paper therefore attempts to investigate this assertion through mathematical connotations/modeling based on some quasiconformal geometrical properties. Also, the study presents some experimental grounds using sample images of pre-surgery and post-surgery faces of different individuals selected from different aesthetic plastic surgery procedures from plastic surgery database and testing using an algorithm coined: conformity to similarity test algorithm for validating our claim. Based on the experimental result, it is evident that the intrinsic structural information of the interior curvature of facial features expressed as edge elements of the global appearance of a face image, is insensitive to the effect of aesthetic surgery induced transformations.
