Individual identification process is a very significant process that resides a large portion of day by day usages. Identification process is appropriate in work place, private zones, banks …etc. Individuals are rich subject having many characteristics that can be used for recognition purpose such as finger vein, iris, face …etc. Finger vein and iris key-points are considered as one of the most talented biometric authentication techniques for its security and convenience. SIFT is new and talented technique for pattern recognition. However, some shortages exist in many related techniques, such as difficulty of feature loss, feature key extraction, and noise point introduction. In this manuscript a new technique named SIFT-based iris and SIFT-based finger vein identification with normalization and enhancement is proposed for achieving better performance. In evaluation with other SIFT-based iris or SIFT-based finger vein recognition algorithms, the suggested technique can overcome the difficulties of tremendous key-point extraction and exclude the noise points without feature loss. Experimental results demonstrate that the normalization and improvement steps are critical for SIFT-based recognition for iris and finger vein , and the proposed technique can accomplish satisfactory recognition performance. Keywords: SIFT, Iris Recognition, Finger Vein identification and Biometric Systems.   © 2018 JASET, International Scholars and Researchers Association

This chapter analyzes a number of vowel harmony systems which have been described or analyzed in terms of aperture (lowering or raising, including complete harmony). This takes us into areas where the literature on vowel harmony discusses cases involving the following binary features: [± high], [± low], [± ATR], and [± RTR]. Raising has been thought of as problematic for unary ‘IUA’ systems as these systems lack a common element for high vowels. This chapter suggests that raising can be attributed to ATR-harmony. The chapter also discusses typological generalizations and analyzes metaphony in Romance languages.
