Quantitative Infrared Thermographic Assessment of Hand Cooling Dynamics During Controlled Contact with Metal Plates
Pengfei Zhu, Hai Zhang, Stefano Sfarra +4
This study investigates the spatiotemporal thermal response of human hands during controlled contact cooling using short wave infrared (SWIR), mid wave infrared (MWIR), and long wa…
Vision-Language Based Expert Reporting for Painting Authentication and Defect Detection
Eman Ouda, Mohammed Salah, Arsenii O. Chulkov +4
Authenticity and condition assessment are central to conservation decision-making, yet interpretation and reporting of thermographic output remain largely bespoke and expert-depend…
Towards Cognitive Defect Analysis in Active Infrared Thermography with Vision-Text Cues
Mohammed Salah, Eman Ouda, Giuseppe Dell'Avvocato +6
Active infrared thermography (AIRT) is currently witnessing a surge of artificial intelligence (AI) methodologies being deployed for automated subsurface defect analysis of high pe…
Field-material coupled neural network: A novel prior-free and data-free inverse problem solver for extracting complex dielectric constant in terahertz band
Pengfei Zhu, Stefano Sfarra, Elena Pivarciova +2
Accurate extraction of the complex dielectric constant in the terahertz (THz) band is essential for material characterization and non-destructive evaluation yet remains challenging…
Masked Sequence Autoencoding for Enhanced Defect Visualization in Active Infrared Thermography
Mohammed Salah, Eman Ouda, Stefano Sfarra +2
Active infrared thermography (AIRT) became a crucial tool in aerospace non-destructive testing (NDT), enabling the detection of hidden defects and anomalies in materials by capturi…
A review of cultural heritage inspection: Toward terahertz from mid-infrared region
Pengfei Zhu, Hai Zhang, Stefano Sfarra +2
This review explores non-invasive imaging (NII) methods covering the mid- and far-infrared to the terahertz spectral regions (up to approximately 1000 um) for the detection and ana…
