Features Understanding for Contactless and Contact-Based Fingerprint Matching

Abstract

A contactless fingerprint is a novel approach to fingerprint recognition, that originated after the covid-19 pandemic because of hygiene issues. In contactless and contact-based fingerprint matching several patterns and features are used to study the ridge-valley patterns of the fingertip. So, the performance of a fingerprint matching system depends on the feature extraction phase. Therefore, feature selection should be done cautiously. Over the period, numerous features and corresponding approaches have been developed for fingerprint recognition. Selecting one or more features is a crucial step in fingerprint identification, which depends upon the database and type of application (like military, commercial, etc.). Hence, the purpose of this study is to do a comprehensive assessment of the available features for matching contact-based and contactless fingerprints.
