Minangkabau And Sunda Tribes Detection Based On Lip Print Pattern Using Discrete Cosine Transform (DCT) And Learning Vector Quantization (LVQ)

Abstract

Abstract—Forensic science is one of the medical sciences to be able to express the identity of an individual from gender to race and ethnicity. In general, forensic science can be interpreted as an application or use of certain knowledge in the interests of law enforcement and justice. In an individual there is a unique pattern that is different from other individuals, even though the specifics will be different for each individual. In general, fingerprints are used but have limitations, namely the lack of resistance to the fingers so that another alternative is lip prints. Lips are an alternative way to get data from individuals. On the lips there are unique patterns that each individual is different, namely the description of sulci on the mucosa of the upper lip and lower lip, as well as fingerprints. Lipstick can be used so that it can help forensic science in solving existing cases. This Paper to identify the Minangkabau and Sundanese tribes so as to minimize the scope of individual searches in the application of forensic science. The method used is the registration of lip print images By using feature extraction method of Discrete Cosine Transform (DCT) and and for classification using Learning Vector Quantization (LVQ).
