Learning What to Generate: A Reinforcement Learning-based Closed-Loop Augmentation Framework for Person Re-identification

ICML 2026poster

Person re-identification (ReID) models are sensitive to long-tail nuisances (e.g., rare viewpoints, occlusions, complex backgrounds), yet current generative augmentation is largely open-loop: prompts/conditions are sampled heuristically without verifying whether the synthesized samples improve ReID …

From Poses to Identity: Training-Free Person Re-Identification via Feature Centralization

CVPR 2025poster

Person re-identification (ReID) aims to extract accurate identity representation features. However, during feature extraction, individual samples are inevitably affected by noise (background, occlusions, and model limitations). Considering that features from the same identity follow a normal distrib…
