New Physics-Guided Diffusion Model Tackles HDR Imaging Artifacts

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel physics-guided diffusion model to address ghosting artifacts in high dynamic range (HDR) imaging, specifically targeting brightness order reversal (BOR) issues that arise from fusing images with large exposure ratios. The proposed algorithm interpolates an initial image using a physics-driven component and then refines it with a diffusion model that analyzes generative models and reduces variations in Pearson correlation. This approach aims to generate more high-frequency information compared to existing neural network-based methods, with experimental results validating its effectiveness. AI

IMPACT This research could lead to improved image quality in HDR photography and videography by reducing common artifacts.

    Physics Guided Diffusion Model Based Exposure Interpolation for High Dynamic Range Imaging

    arXiv:2610.37135v1 Announce Type: new Abstract: Ghosting artifacts are an open problem for popular multi-shot based high dynamic range (HDR) imaging. An effective solution is to capture two large-exposure-ratio (LER) standard dynamic range (SDR) images simultaneously via a single…
