Crack Instance Segmentation Dataset for Civil Infrastructure

Dataset Overview:This dataset is designed for crack instance segmentation research and consists of three components: CrackTree200: A public dataset for crack detection. CrackTree260: A public dataset for crack detection. crack-seg-new: A curated dataset specifically optimized for high-precision evaluation. Key Feature - High-Fidelity Annotations:Unlike traditional datasets that often use coarse polygon approximations, the validation and test subsets of crack-seg-new have been manually re-annotated with fine-grained vertex editing. This ensures that the masks accurately capture thin lateral branches, hairline extensions, and complex bifurcation topologies of cracks. Contents: crack-seg-new/: Contains refined validation and test images and their corresponding high-precision masks. CrackTree200/: Original public images and annotations. CrackTree260/: Original public images and annotations.
