Implementation of 2DPCA and SOM Algorithms to Determine Sex According to Lip Shapes

Lips are part of body parts in facial area which are unique in shapes and may have different patterns. Pattern or shape of lips can be used as an individual identity, either for a live or deceased person. Forensic science is a branch of medical science which utilizes lip shape to determine the identity of a person, including their sex. Determination of sex using image of lip shape using 2DPCA and SOM algorithms was successful in classifying the sex of a person, as male or female, using desktop-based Java programming language. This study employed 90 lip images, consisting of 60 training data (30 of male and 30 of female) and 30 testing data of male and female. The testing result showed accuracy rate of 76,66% with a rate of 0,9 and maximum iteration of 10000.
