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

Sensors, 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 ...

Feasibility of Pulsed Thermography for Moisture Estimation

Journal of Applied Research and Technology, 2022
The dehydration of farm products provides farmers an opportunity to preserve their products longer and simultaneously earn more profit from them. Nevertheless, traditionally the quality of the dehydrated products has been determined by the use of invasive methods, for example, through manual measurements with a Vernier caliper and a micrometer, has its
