A physics-informed framework for feature extraction and defect segmentation in pulsed infrared thermography

Engineering Failure Analysis
This paper presents a robust and interpretable methodology for defect detection in active infrared thermography data applied to polyvinyl chloride (PVC) specimens. Our approach integrates a physics-based cooling model to describe the transient thermal response of each pixel, from which five primary temporal features are extracted via least-squares ...

Assessment of eggs freshness by means of pulsed infrared thermography

Proceedings of the 2018 International Conference on Quantitative InfraRed Thermography, 2018
The paper examines the topic of identifying eggs freshness through an original approach based on pulsed thermography. The proposed method relies on a short thermal stimulation performed by means of a xenon flash, which rises up the temperature of the egg of less than 1 degrees C.
