Gradient transformer Self-Attention U-Net for enhanced crack detection in concrete bridges
This paper introduces the Gradient Transformer Attention U-Net (GTAU-Net) model, a novel deep learning approach that significantly advances crack detection in bridge components. Unlike conventional attention-based U-Nets, GTAU-Net introduces a Quantum Fused Filter (QFF) to pre-process images by integrating multiple edge and gradient patterns through a quantum-inspired hybrid filtering strategy. It further computes Gradient Saliency Scores (GSS) to dynamically guide the self-attention mechanism, enabling more precise localization and feature extraction. Through this dual enhancement, GTAU-Net effectively handles varying crack sizes, shapes, orientations, and environmental conditions. Experimental results demonstrate that GTAU-Net achieves an impressive 99.42% accuracy significantly outperforming existing models and measures crack lengths, highlighting sustainability. This research contributes to the advancement of automated crack detection technology, offering a promising solution for enhancing infrastructure safety and durability. To promote transparency and reproducibility, the code and dataset used in this study are publicly available at Zenodo: https://doi.org/10.5281/zenodo.15617661.

Computer Vision Breakthroughs
This research leverages cutting-edge computer vision techniques for highly accurate crack detection. The introduction of the Quantum Fused Filter (QFF) represents a significant advancement in image preprocessing, allowing for the integration of multiple edge and gradient patterns through a quantum-inspired hybrid filtering strategy. This results in superior feature extraction, essential for identifying even subtle cracks in complex environments. The Gradient Saliency Scores (GSS) further refine the process by dynamically guiding the self-attention mechanism to focus on critical pixel regions, enhancing the model's ability to localize and characterize cracks with unprecedented precision across various visual conditions.
Advanced Deep Learning Architectures
The GTAU-Net model introduces a novel deep learning architecture that combines the strengths of transformer networks with U-Net. This hybrid approach enables the model to capture both local spatial details (via U-Net's convolutional layers) and long-range contextual dependencies (via the transformer's self-attention mechanisms). The integration of GSS within the self-attention block allows for adaptive weighting of features, prioritizing crack-relevant information and suppressing noise. This innovative design addresses the limitations of conventional deep learning models in handling diverse crack characteristics and environmental interferences, leading to significantly improved accuracy and robustness in real-world applications.
Revolutionizing Infrastructure Safety
The implications of GTAU-Net for infrastructure monitoring are profound. By automating crack detection with high precision and reliability, the model offers a powerful tool for maintaining bridges and other critical structures. Early and accurate identification of cracks is vital for proactive maintenance, preventing catastrophic failures, extending asset lifespan, and ensuring public safety. The model's robustness to varying environmental conditions makes it suitable for diverse deployment scenarios, contributing directly to sustainable infrastructure management by optimizing inspection efficiency and resource allocation. This paves the way for a new era of predictive maintenance in civil engineering.
