PCD-Net: prior-context collaborative learning for robust facial expression recognition under noisy labels

Abstract Noisy annotations and class imbalance commonly coexist in real-world facial expression recognition (FER), making hard but correctly labeled minority-class samples difficult to distinguish from unreliable training samples. Existing noisy FER approaches mainly improve robu...

Pseudo defect guided meta calibration for few shot industrial defect segmentation

Few-shot industrial defect segmentation aims to localize unseen defects from only a few defect-free reference images, but remains challenging because no positive anomaly examples are available and defects are often subtle, irregular, and embedded in complex textures. We propose P...
