Complementary Global–Local Feature Fusion and Ensemble Refinement for Facial-Expression Recognition on FER2013

Facial-expression recognition (FER) on FER2013 remains challenging because of low-resolution images, class imbalance, and label ambiguity. This study presents a global–local feature-fusion framework that integrates complementary representations with validation-based ensemble refinement. A frozen DINOv2 ViT-Base capture...
