Researchers have developed GTF, an omnidirectional EPI Transformer designed for light field image super-resolution. This new model explicitly incorporates diagonal epipolar geometry, which was previously underexplored in similar methods. GTF achieved strong performance on standard benchmarks, reaching 32.78 dB, and a lightweight variant, GTF-Tiny, also demonstrated efficiency with a low parameter count. The GTF model and its variants secured competitive rankings in the NTIRE 2026 Light Field Image Super-Resolution Challenge. AI
