Thermal Imaging as a Biometrics Approach to Facial Signature Authentication

---

Abstract—A new thermal imaging framework with unique featureextractionandsimilaritymeasurementsforfacerecognitionis presented.Theresearchpremiseistodesignspecializedalgorithms thatwouldextractvasculatureinformation,createathermalfacial signature, and identify the individual. The proposed algorithm is fullyintegratedandconsolidatesthecriticalstepsoffeatureextractionthroughtheuseofmorphologicaloperators,registrationusing theLinearImageRegistrationTool,andmatchingthroughunique similarity measures designed for this task. The novel approach at developing a thermal signature template using four images taken at various instants of time ensured that unforeseen changes in the vasculature over time did not affect the biometric matching processastheauthenticationprocessreliedonlyonconsistentthermal features.Thirteensubjectswereusedfortestingthedevelopedtechniqueonanin-housethermalimagingsystem.Thematchingusing thesimilaritymeasuresshowedanaverageaccuracyof88.46%for skeletonized signatures and 90.39% for anisotropically diffused signatures. The highly accurate results obtained in the matching process clearly demonstrate the ability of the thermal infrared system to extend in application to other thermal-imaging-based systems. Empirical results applying this approach to an existing database of thermal images prove this assertion.
