New framework enables hyperspectral image classification without source data

Researchers have developed a new topology-aware learning framework to address the challenges of cross-scene hyperspectral image classification when source domain data is unavailable. This method utilizes entropy momentum pseudo-labeling to refine assignments and employs contextual neighborhood topology to capture the target feature space's geometric structure. Experiments on three scenarios demonstrate that this source-free approach outperforms existing state-of-the-art methods, highlighting the importance of topology-aware modeling for accurate classification without source data.
