Researchers have introduced CO-EVO, a novel federated framework designed to improve person re-identification across different domains without compromising data privacy. The system addresses challenges posed by varying visual styles across decentralized clients by employing a co-evolutionary mechanism. This approach combines Camera-Invariant Semantic Anchoring to create domain-agnostic identity anchors and Global Style Diversification to expand the training data's visual range. CO-EVO has demonstrated state-of-the-art performance in experiments, highlighting the importance of balancing semantic purification with style expansion for robust cross-domain generalization. AI
