Researchers have introduced D$^{2}$R$^{2}$OSR, a new framework designed to improve the resolution of omnidirectional images (ODIs) that suffer from real-world degradations and geometric distortions. This method explicitly models the complex imaging pipeline, including fisheye capture and Equirectangular Projection (ERP), by incorporating a Perspective Projection Representation (PPR) alongside the standard ERP branch. The framework also includes a Degradation-Specific Module (DSM) to jointly address ERP-induced distortions and PPR-specific degradations. Experiments show that D$^{2}$R$^{2}$OSR achieves state-of-the-art results in omnidirectional image super-resolution while maintaining computational efficiency. AI
