Literature Review on Fingerprint Level 1 and Level 2 Features Enhancement to Improve Quality of Image

Abstract

Biometrics is the one most popular property in human distinguishing proof based on physical or behavioral features. The different physiological characteristics are Fingerprint, DNA, Face, hand,retina, ear features, and odor, where as behavioral characteristics or features are typing rhythm,gait, gesture, and voice with the basic premise that all are unique and all human beings areidentified by these intrinsic traits. In the physiological traits, Fingerprint is most commonlyutilized the biometric feature in diverse fields for identification and verification purpose.Fingerprint features can be separated into three noteworthy classifications in view of thegranularity at which they are removed as level 1, level 2, and level 3 features. Level 1 featurecontains macro details, which are easily extractable and include orientation filed, ridge frequency filed and pattern configuration. Only these global features or Level 1 features are not sufficient touniquely identify or recognize, but if these features are used along with level 2 or level 3 features, that can make the fingerprint recognition system more robust and secure. Level1 features are used for image enhancement and orientation purpose. In this paper, we made asurvey of existing literature on Level 1 features and try to analyze other researcher's contributionto this field.
