Biometrics which use of human physiological characteristics for identifying an individual is now a widespread method of identification and authentication. Biometric identification is a technology which uses several image processing techniques and describes the general procedure for identification and verification using feature extraction, storage and matching from the digitized image of biometr...

Biometrics refers to a real-time identification system that is used in the identification of a person using a specific physical or behavioral characteristic which is compared with a library of characteristics of many other people.This is done using a biometric scanning device (tongue-print scan) which captures the user’s biometric data such as the tongue-print scan and converts it into a digita...

FT-IR spectroscopy is the basic finger-print method for qualitative and quantitative analysis of nitrogen, boron, hydrogen impurities in natural synthetic diamonds. In measurements impurity concentrations, external standard samples are required calibration procedure during analysis. this study, double-phonon mid-IR absorption coefficient optical phonons diamond host matrix, robust internal stan...
