This MATLAB-based implementation includes sample images and is ready to run (requires path modification). Designed for crack detection in bridge decks and road surfaces, the code features detailed function descriptions and algorithmic explanations. Key implementations include frequency estimation of regular stripe patterns in road backgrounds and frequency-domain filtering to effectively remove noise near estimated frequencies while preserving target cracks. The current version provides basic detection functionality with room for improvement, serving as a demonstrative prototype. Interested developers are welcome to enhance and adapt this codebase - please contact me for collaboration opportunities.
