Researchers have developed CrossTimeEdit, a novel framework for generating historical street-view imagery by editing recent views. This approach utilizes a new dataset, VIGOR-his, comprising over 43,000 location-level quadruplets across 11 cities. The model reformulates historical generation as an editing task, using recent street views for viewpoint and unchanged appearance constraints, and temporal satellite differences as evidence of change. Trained with reinforcement learning and fine-tuning on FLUX.2 [Klein] 4B, CrossTimeEdit demonstrated a 17.12% improvement over its baseline in areas like instruction alignment, background preservation, and quality.
