A Cheiloscopic Approach for Unique Identification Among Indian Subpopulation
A biometric is formed on an individual’s behavioural or physical features. The main approach is to uniquely identify humans. Identification by biometric factors finishes the complications related with customary approaches used for human identification. The biometric methods that are most commonly being used today are fingerprints, eye retina, iris, etc. This paper shows that just like fingerprints and lip prints are unique in nature and hence can be used as one of the measures to recognize individuals. Also, this paper shows that the nature of lips of an individual varies according to state one belongs to. The lip print samples are taken from different people in different states. After the enhancement of image, existing Sobel edge detection algorithm has been applied to detect the edges of lips. Thereafter, the numValue, i.e. featureValue of the lip print, is extracted and stored which depicts the uniqueness. The graphs have been plotted and examined.
