MATLAB Implementation of Surface Crack Detection Algorithm

Abstract: This paper proposes a surface crack detection algorithm based on digital image processing techniques. The algorithm utilizes advanced image processing methods to accurately identify crack characteristics including position and length. When implemented in MATLAB, this crack detection approach can be integrated into automated inspection systems and crack propagation monitoring applications, significantly reducing labor time and intensity while improving measurement accuracy. The implementation includes key image processing functions such as edge detection, morphological operations, and feature extraction algorithms.
