GMODiff framework refines HDR reconstruction using diffusion models

Researchers have developed GMODiff, a novel one-step diffusion framework for High Dynamic Range (HDR) reconstruction. This method reframes HDR reconstruction as a gain map refinement problem, leveraging pre-trained Latent Diffusion Models (LDMs) to encode extended dynamic range while maintaining the same bit depth as standard low dynamic range images. GMODiff addresses limitations of direct LDM application by mitigating content hallucination and reducing inference costs, achieving a 100x speed improvement over previous LDM-based approaches while maintaining high perceptual quality and structural accuracy. AI

IMPACT This new diffusion-based approach significantly speeds up HDR reconstruction and improves quality by leveraging pre-trained models.

    GMODiff: One-Step Gain Map Refinement with Diffusion Priors for HDR Reconstruction

    arXiv:2512.16357v3 Announce Type: replace Abstract: Pre-trained Latent Diffusion Models (LDMs) have recently shown strong perceptual priors for low-level vision tasks, making them a promising direction for multi-exposure High Dynamic Range (HDR) reconstruction. However, directly …
