Description Sex determination in human skeletal remains is one of the most important steps in forensic pathology and skeletal anthropology. In addition to the pelvis, the skull is the most commonly used skeletal site to determine males and females, and the supraorbital region which includes the supraorbital margin is considered a crucial sexually dimorphic trait. Unlike the visual or morphoscopic approach, where sex is determined through the visual and tactile assessment, the present study aims to propose a methodology based on an objective quantification of the sexually dimorphic features. Using Wavelet Transform as a multi-scale tool allows measuring shape variations which are hidden at different scales of resolution. Our analysis has shown good results which may contribute to sex determination and allow experts to construct biological profiles of human skeleton as well as to monitor the geographical and temporal variations within and among populations.
