Researchers have introduced GB-LSR, a novel local spectral image representation designed for continuous image reconstruction and super-resolution. This method partitions images into patches, with each patch containing coefficients for a truncated Fourier basis predicted from shared encoder features. A single, globally shared bandwidth parameter is used across all patches and images, allowing for reconstruction at any continuous coordinate with a fixed cost independent of image size. GB-LSR demonstrates superior performance in terms of PSNR and LPIPS compared to existing methods while operating at a significantly lower inference cost. AI
