Label Scarcity Reveals Architecture-Dependent Robustness in CNN-Based Casting Defect Detection
Deep learning for automated visual inspection in manufacturing is often limited by the cost of labeling large image datasets. Using 7,348 casting images, we evaluated how three CNN architectures, ResNet18, ResNet50, and MobileNetV3-Small, tolerate progressively reduced labeling b…
