Researchers have developed a novel unsupervised framework for cross-domain day-night re-identification. This method leverages a two-stage training strategy that combines prompt learning with prototype-based representation learning. By utilizing vision-language models to generate textual prompts and aligning visual features with these prompts, the system establishes identity correspondences across day and night scenes without manual labeling. Experiments show this approach achieves performance comparable to state-of-the-art fully supervised methods. AI
