Training-Free Semantic-Edge Response Decoding of SAM3 for Cross-Domain Infrastructure Crack Segmentation
Shipeng Liu, Zhanping Song, Liang Zhao, Dengfeng Chen
Cross-project crack segmentation is hindered by variations in materials, imaging conditions, crack morphology, and background interference. Text-promptable foundation models reduce task-specific training, but SAM3's final region proposals may suppress, truncate, or distort weak a…
