Single-frame crack segmentation for laboratory fracture images: concrete and cement-mortar cubes under uniaxial compression, coal / sandstone Brazilian discs under SHPB impact. Trained on the CrackEvo benchmark (China University of Mining and Technology-Beijing laboratory experiments) plus public crack datasets (CFD, CrackTree, DeepCrack, 40k) used for training only. Large images are processed with 512-px sliding windows (stride 384, logits averaged). About 45 ms per tile on a desktop CPU with ONNX Runtime. Exact-pixel IoU is limited by centre-line ground truth on two of the sources; tolerant F1 reflects localisation quality. Cross-material generalisation (unseen sandstone) drops to IoU…
