Researchers have developed a new framework called MDC-guided Cross-modal Prior Transfer (MCPT) to improve the transfer of knowledge from optical imagery to Synthetic Aperture Radar (SAR) data for Generalized Category Discovery (GCD). The MCPT framework introduces a Modal Discrepancy Curve (MDC) to quantify cross-modal differences in the frequency domain. This approach utilizes Adaptive Frequency Tokenization (AFT) and Frequency-aware Expert Refinement (FER) to refine features and align embeddings across modalities. Experiments show that this method achieves state-of-the-art performance on SAR-GCD tasks by enabling more effective adaptation of optical prior to SAR imagery. AI
