Effective compression algorithms for pulsed thermography data

open access: yes, 2022
S.201-218Two compression algorithms for the image sequences generated by pulsed-transient thermography for non-destructive testing were developed. The first algorithm allows to balance the quality of the original measurement data reproduction against a ...

Emissivity Correction and Thermal Pattern Reconstruction in Eddy Current Pulsed Thermography

open access: yesSensors, 2023
Emissivity variations are one of the most critical challenges in thermography technologies; this is due to the temperature calculation strongly depending on emissivity settings for infrared signal extraction and evaluation.

Defect Shape Detection and Defect Reconstruction in Active Thermography by means of Two-Dimensional Convolutional Neural Network as well as Spatiotemporal Convolutional LSTM Network

open access: yes, 2022
126144A neural network (NN) for semantic segmentation (U-Net) was used for the detection of crack-type defects from thermography sequences. For this task, data sequences of forged steel parts were acquired through induction thermography and the ...

Enhanced Infrared Image Processing for Impacted Carbon/Glass Fiber-Reinforced Composite Evaluation

open access: yesSensors, 2017
In this paper, an infrared pre-processing modality is presented. Different from a signal smoothing modality which only uses a polynomial fitting as the pre-processing method, the presented modality instead takes into account the low-order derivatives to ...
