Researchers have investigated how data augmentation techniques impact the performance of deep learning models in classifying laser speckle patterns for material identification. Their study, using ResNet18 and EfficientNet-B0 on the SensiCut dataset, found that standard augmentation methods like Gaussian blur and independent noise are detrimental because they disrupt the crucial structural information in speckle patterns. Conversely, spatially correlated perturbations that preserve the speckle organization significantly improved model robustness. The findings suggest that physics-aware augmentation design, focusing on structural preservation, is key for effective coherent optical sensing applications. AI
