Abstract

En 中文

• A framework integrates component instance segmentation and OBB damage detection. • A convex hull-based OBB labeling standardizes annotation for complex-shaped damage. • A structural knowledge-based augmentation boosts detection under data scarcity. • A semantic-edge branch improves RC component segmentation via boundary supervision.
