FH-Net: Frequency-domain and hierarchical dual enhancement for few-shot surface defect segmentation
In real-world industrial manufacturing, surface defect segmentation is severely challenged by the extreme scarcity of annotated defect samples, which renders exhaustively supervised approaches impractical. Although meta-learning based few-shot segmentation paradigms have made initial progress, existing methods still su...
