A Defect Detection Method for Rail Ultrasonic B-Scan Images Based on a Multi-Scale Dense Attention Network

Rail internal defects pose significant threats to railway operational safety, and ultrasonic B-scan imaging provides an effective nondestructive testing approach for visualizing subsurface rail conditions. However, manual interpretation of B-scan images is time-consuming and depends heavily on operator experience. To o...

FH-Net: Frequency-domain and hierarchical dual enhancement for few-shot surface defect segmentation

A novel few-shot surface defect segmentation method termed FH-Net is proposed, which aims to achieve high-precision segmentation of previously unseen categories using only a limited number of annotated samples and enriches support set feature diversity through foreground- and global-level amplitude perturbations in the...
