English(EN) Unlocking Optical Prior: Spectrum-Guided Knowledge Transfer for SAR Generalized Category Discovery

研究人员开发用于 SAR 广义类别发现的频谱引导知识迁移

研究人员开发了一个名为 MDC-guided Cross-modal Prior Transfer (MCPT) 的新框架,以改进从光学图像到合成孔径雷达 (SAR) 数据进行广义类别发现 (GCD) 的知识迁移。MCPT 框架引入了模态差异曲线 (MDC) 来量化频域中的跨模态差异。该方法利用自适应频率分词 (AFT) 和频率感知专家细化 (FER) 来细化特征并对齐跨模态的嵌入。实验表明,通过实现光学先验到 SAR 图像的更有效适应,该方法在 SAR-GCD 任务上取得了最先进的性能。 AI

影响 增强了 SAR 图像的跨模态迁移学习,可能提高了标签稀缺领域的性能。
