Revolutionizing Infrastructure Inspection with AI-Powered Crack Segmentation
This study introduces IEM-UNet, a lightweight crack segmentation network that significantly improves crack detection accuracy while reducing model parameters. It innovatively combines CNN and an importance-enhanced Mamba model to address challenges in complex crack morphologies and computational costs. The network features a dual-branch design for synergistic feature extraction, with a dynamic scanning module in the Mamba branch for adaptive path adjustment based on crack geometries, and a CNN branch for fine-grained local features. An attention-guided module fuses these complementary features, preserving both microstructural details and macroscopic relationships. Extensive experiments on three public datasets (Crack500, Crack Tree260, and CrackForest) show that IEM-UNet outperforms advanced methods in accuracy with substantial reductions in parameters and computational complexity, making it suitable for resource-constrained environments.

Overall Architecture Overview
The IEM-UNet employs a symmetric U-Net encoder-decoder with a dual-branch module combining CNNs and Mamba for hybrid feature extraction. The Mamba branch uses an importance-enhanced dynamic scanning module to adaptively adjust scanning paths, enhancing global crack feature perception, while the CNN branch captures fine-grained local features like edges and textures. A multi-scale feature aggregation module integrates these local and global insights for precise and fast segmentation.
Importance-Enhanced Visual State Space (IE-VSS)
The Importance-Enhanced Visual State Space (IE-VSS) module is a parallel fusion architecture integrating CNN and VSS. The CNN branch extracts local features with 3x3 DepthWise convolutions. The VSS branch, improved with IE-Scan, dynamically adjusts scanning paths based on crack importance, overcoming limitations of static scanning for complex crack morphologies.
Dynamic Scanning (IE-scan)
Traditional Mamba models use fixed horizontal-vertical scanning. IE-scan dynamically filters key crack regions to reconstruct scanning paths, adapting to irregular crack shapes like tree-like or mesh-like patterns. It measures feature importance based on activation intensity, sorting blocks to prioritize salient regions, which enhances sensitivity and reduces background interference.
Attention-Gated (AG) Module for Feature Fusion
The AG module fuses local features from the CNN branch (fine details, but prone to noise) and global features from the improved Mamba model (overall structure, spatial relationships). It assigns adaptive pixel-wise weights to integrate information, preserving crack details and macroscopic relationships while preventing dilution by redundant information.
