Pyramid Inter-Attention for High Dynamic Range Imaging
Sensors, 2020 This paper proposes a novel approach to high-dynamic-range (HDR) imaging of dynamic scenes to eliminate ghosting artifacts in HDR images when in the presence of severe misalignment (large object or camera motion) in input low-dynamic-range (LDR) images ...

High dynamic range and super-resolution from raw image bursts [PDF]
ACM Transactions on Graphics, 2022 Photographs captured by smartphones and mid-range cameras have limited spatial resolution and dynamic range, with noisy response in underexposed regions and color artefacts in saturated areas.

Pyramidal Feature Adjustment Networks for High Dynamic Range Imaging of Dynamic Scenes
IEEE Access, 2023 Multi-exposure high dynamic range (HDR) imaging aims to generate an HDR image from multiple low dynamic range (LDR) images. There are two main challenges in this task; camera and object motions causing ghost artifacts and over/under-exposure areas having

Unpaired Learning for High Dynamic Range Image Tone Mapping [PDF]
IEEE International Conference on Computer Vision, 2021 High dynamic range (HDR) photography is becoming increasingly popular and available by DSLR and mobile-phone cameras. While deep neural networks (DNN) have greatly impacted other domains of image manipulation, their use for HDR tone-mapping is limited ...

High-dynamic-range imaging for cloud segmentation [PDF]
Atmospheric Measurement Techniques, 2018 Sky–cloud images obtained from ground-based sky cameras are usually captured using a fisheye lens with a wide field of view. However, the sky exhibits a large dynamic range in terms of luminance, more than a conventional camera can capture. It is thus

Perceptual Tone Mapping Model for High Dynamic Range Imaging
IEEE Access, 2023 One of the key challenges in tone mapping is to preserve the perceptual quality of high dynamic range (HDR) images when mapping them to standard dynamic range (SDR) displays.

Exposure-Structure Blending Network for High Dynamic Range Imaging of Dynamic Scenes
IEEE Access, 2020 This paper presents a deep end-to-end network for high dynamic range (HDR) imaging of dynamic scenes with background and foreground motions. Generating an HDR image from a sequence of multi-exposure images is a challenging process when the images have ...

Generation of high dynamic range for enhancing the panorama environment
Bulletin of Electrical Engineering and Informatics, 2021 This paper presents a methodology for enhancement of panorama images environment by calculating high dynamic range. Panorama is constructing by merge of several photographs that are capturing by traditional cameras at different exposure times ...

Deep Joint Demosaicing and High Dynamic Range Imaging Within a Single Shot [PDF]
IEEE transactions on circuits and systems for video technology (Print), 2021 Spatially varying exposure (SVE) is a promising choice for high-dynamic-range (HDR) imaging (HDRI). The SVE-based HDRI, which is called single-shot HDRI, is an efficient solution to avoid ghosting artifacts.
