High Dynamic Range Imaging with Multiple Artifact Suppression and Multilevel Fusion

Shuju Caiji Yu Chuli
Due to the limitations of existing imaging equipment， it is difficult to obtain high dynamic range （HDR） images directly. High dynamic range imaging technology is designed to generate HDR images by processing low dynamic range （LDR） images. Most existing

Parallel Implementation of a Real-Time High Dynamic Range Video System [PDF]

, 2014
. This article describes the use of the parallel processing capabilities of a graphics chip to increase the processing speed of a high dynamic range (HDR) video system. The basis is an existing HDR video system that produces each frame from a sequence of

Blur to Brilliance: Neuromorphic Data Guided Deblurring and HDR Novel View Synthesis

IEEE Access
Event cameras are neuromorphic sensors that asynchronously capture intensity changes, making them highly effective for fast motion and challenging lighting conditions. While Neural Radiance Fields (NeRFs) have revolutionized 3D scene representation, they

HDR Image Quality Enhancement Based on Spatially Variant Retinal Response

EURASIP Journal on Image and Video Processing, 2010
There is a growing demand for being able to display high dynamic range (HDR) images on low dynamic range (LDR) devices. Tone mapping is a process for enhancing HDR image quality on an LDR device by converting the tonal values of the original image from ...

DeLight-Net: Decomposing Reflectance Maps into Specular Materials and Natural Illumination

, 2016
In this paper we are extracting surface reflectance and natural environmental illumination from a reflectance map, i.e. from a single 2D image of a sphere of one material under one illumination. This is a notoriously difficult problem, yet key to various

Overview of ghost correction for HDR video stream generation

, 2015
International audienceMost digital cameras use low dynamic range image sensors, these LDR sensors can capture only a limited luminance dynamic range of the scene[1], to about two orders of magnitude (about 256 to 1024 levels).

HDR-NSFF: High Dynamic Range Neural Scene Flow Fields

Radiance of real-world scenes typically spans a much wider dynamic range than what standard cameras can capture. While conventional HDR methods merge alternating-exposure frames, these approaches are inherently constrained to 2D pixel-level alignment, often leading to ghosting artifacts and temporal inconsistency in dynamic scenes.
