High Quality 3D Fingerprint Acquisition Using Novel Sub-windowBased Structured Light Illumination Approach

摘要

Fingerprint identification is one of the most prolific and well-regarded modalities in the field of biometrics for its high recognition rates. Fingerprints remain consistent throughout a person's lifetime and are relatively simple and inexpensive to capture with techniques ranging from inked fmgerprint cards to Livescan devices. In this paper, we present an algorithm and a working device that is capable of capturing high quality 3D fingerprints based on Structured Light Illumination using a novel approach called the sub-window technique. The various benefits of this unique approach and applications in fingerprint biometrics are presented.
