Research questionHow can single-image super-resolution recover global structure and localized aperiodic detail despite periodic spectral bases?Single-image super-resolution must infer fine high-resolution detail while maintaining coherent global structure. Periodic spectral representations can capture broad dependencies but may miss irregular, localized variations.
