New discrete diffusion model enhances image super-resolution

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced DiMOO-SR, a novel framework for photo-realistic image super-resolution that leverages discrete diffusion models. This approach addresses challenges in discrete diffusion for super-resolution, specifically the under-representation of rare visual tokens and spatial inconsistencies during decoding. DiMOO-SR employs Inverse Frequency Sampling during training to prioritize important but under-represented tokens and Spatial Consistency Ranking during inference to refine token confidence and improve structural coherence. Experiments on standard benchmarks show that DiMOO-SR can achieve competitive perceptual quality with a limited number of parallel decoding steps. AI

IMPACT This research advances discrete diffusion models for image generation, potentially improving the quality and efficiency of super-resolution tasks.

    Rarity-Aware Discrete Diffusion with Spatially Consistent Decoding for Photo-Realistic Image Super-Resolution

    arXiv:2607.17612v1 Announce Type: new Abstract: Continuous diffusion models have become the dominant paradigm for photo-realistic image Super-Resolution (SR), but they typically formulate reconstruction as continuous signal-level denoising and incorporate semantic priors through …
