RASLF: Representation-Aware State Space Model for Light Field Super-Resolution
This work addresses the limitations of existing state-space-model-based light field super-resolution methods, which often fail to effectively integrate complementary information across multiple representations, leading to loss of texture details and misalignment in view geometry. To overcome these challenges, we propose a representation-aware state space framework that explicitly models structural relationships among diverse light field representations—such as epipolar plane images and sub-aperture views—to enable accurate and efficient super-resolution reconstruction. Key innovations include a progressive geometric refinement module for view alignment correction, a representation-aware asymmetric scanning mechanism tailored to heterogeneous representation characteristics, and a dual-anchor hierarchical feature aggregation strategy. Extensive experiments demonstrate that our method achieves state-of-the-art reconstruction performance on multiple public benchmarks while maintaining superior computational efficiency.
