To address this, we propose a two-stage framework called RobustSeg, which enhances multi-modal robustness through two key components: the Hybrid Prototype Distillation Module (HPDM) and the Representation Regularization Module (RRM). In the first stage, RobustSeg pre-trains a multi-modal teacher model using complete modalities. In the second stage, a student model is trained with random modality dropout while learning from the teacher via HPDM and RRM. HPDM transforms features into compact prototypes, enabling cross-modal hybrid knowledge distillation and mitigating bias from missing modalities. RRM reduces representation discrepancies between the teacher and student by optimizing functional entropy through the log-Sobolev inequality. Extensive experiments on three public benchmarks demonstrate that RobustSeg outperforms previous state-of-the-art methods, achieving improvements of +2.76%, +4.56%, and +0.98%, respectively.
