Lip Imprint Based Biometric Identification: A Survey [ ]

The aim of this paper is to present a survey on different approaches to use human lip-imprints as a mode of Biometric Identification. The different approaches discussed in the series of papers could be classified broadly into two categories: Manually Implemented Methods and Automated methods based on Digital Image Processing and other machine learning algorithms. The method of accepting input imprints and the method of matching those imprints are distinct in different approaches, but basis of nearly all the approaches is the study of the groove patterns present in the lip imprints.
