CRACK500_ex: Derived Patch-Based Dataset for Morphology-Aware Crack Analysis

CRACK500_ex is a derived, patch-based crack-analysis dataset created from the original CRACK500 dataset for morphology-aware crack analysis. This release contains patch-level .npz samples organized into train, validation, and test splits. Each sample stores multiple derived annotation layers intended for crack-structure analysis and downstream explainable inspection workflows. The dataset is organized into:- train- val- test Patch counts in this release:- Train: 2396- Validation: 448- Test: 1472 Each .npz file contains derived data fields such as:- mask_crack- mask_noise- mask_skeleton- mask_branch- features CRACK500_ex is intended for academic and research use in crack detection, crack segmentation, skeleton extraction, morphology-aware crack analysis, branch/structural-label analysis, and explainable infrastructure inspection workflows. CRACK500_ex is derived from the original CRACK500 dataset. Users should cite both this derived dataset release and the original CRACK500 source when using this dataset.
