Researchers have developed MambaRaw, a new framework for reconstructing high-resolution raw images using JPEG previews. This method leverages State Space Models (SSMs) to efficiently estimate entropy parameters, overcoming the computational expense of traditional attention mechanisms in high-resolution contexts. MambaRaw incorporates a Spatial-Energy Coupled Context Modeling mechanism with TileMambaBlock for selective scanning and Energy-Aware Refinement (EAR) to enhance feature representation. Experiments on Sony, Olympus, and Samsung datasets demonstrate that MambaRaw achieves state-of-the-art results in JPEG-guided raw reconstruction, offering significant improvements in PSNR and reducing coding latency.
