Improved Fingerprint Matching by Distortion Removal

摘要

Fingerprint recognition is a well-researched problem, and there are several highly accurate systems commer- cially available. However, this biometric technology still suffers from problems with the handling of bad quality prints. Recent research has begun to tackle the problems of poor quality data. This paper takes a new approach to one problem besetting finger- prints-that of distortion. Previous attempts have been made to ensure that acquired prints are not distorted, but the novel approach presented here corrects distortions in fingerprints that have already been acquired.
