Method and apparatus for denoising ray tracing image

Patent published on the 2026-05-28 in US under Ref US20260148351 by SAMSUNG ELECTRONICS CO LTD [KR] (Kang Nahyup [kr], Kim Hanjun [kr], Jang Seokhwan [kr], Jung Hwiryong [kr], Hong Seokpyo [kr])

Abstract: A method of denoising a ray tracing image includes obtaining an irradiance image by receiving a rendering result, by separating the irradiance image for each frequency component, performing downsampling on the separated irradiance image to to obtain a first downsampled irradiance image and a second downsampled irradiance image, obtaining a filter weight using a denoising look-up table (LUT) based on pixel information, the first downsampled irradiance image and the second downsampled irradiance i[...]


Our summary: The method involves obtaining an irradiance image from a rendering result and separating it into frequency components. It then performs downsampling and uses a denoising look-up table to obtain filter weights for a weighted sum. Finally, it upscales the denoised image and combines it with an albedo image to produce the final output.

A Real&ndash;Virtual Fusion Approach with Inconsistency Mitigation

Published on 2026-02-03 by Sukwoo Jung, Myeongseop Kim, Jean Oh, Jonghwa Kim, Kyung-Taek Lee @MDPI

Abstract: Autonomous driving systems rely on vast and diverse datasets for robust object recognition. However, acquiring real-world data, especially for rare and hazardous scenarios, is prohibitively expensive and risky. While purely synthetic data offers flexibility, it often suffers from a significant reality gap due to discrepancies in visual fidelity and physics. To address these challenges, this paper proposes a novel real&amp;ndash;virtual fusion framework for efficiently generating highly reali[...]


Our summary: This paper presents a real-virtual fusion framework for generating realistic augmented datasets for autonomous driving. It synchronizes real-world data with a digital twin environment to inject virtual objects into real images. The approach focuses on inconsistency mitigation to enhance visual fidelity and improve perception model generalization.
