Carbon fiber-reinforced polymer (CFRP) laminates are widely used in aerospace, automotive, and infrastructure industries due to their high strength-to-weight ratio. However, defect detection CFRP remains challenging, particularly low signal-to-noise ratio (SNR) conditions. Conventional segmentation methods often struggle with noise interference signal variations, leading reduced accuracy. In this study, we evaluate the impact of thermal image preprocessing on improving inspected via pulsed...
