Research on Synthetic Data Methods and Detection Models for Micro-Cracks [PDF]
SensorsMicro-crack detection on concrete surfaces is challenging because labeled micro-crack data are scarce, crack cues are extremely weak (often only a few pixels wide), and complex backgrounds (e.g., non-uniform illumination, shadows, and stains) degrade ...
