Non-Iterative Tone Mapping With High Efficiency and Robustness [PDF]
IEEE Access, 2018 This paper proposes an efficient approach for tone mapping, which provides a high perceptual image quality for diverse scenes. Most existing methods, optimizing images for the perceptual model, use an iterative process and this process is time consuming.

Learning Tone Curves for Local Image Enhancement
IEEE Access, 2022 Image enhancement methods can be formulated as global transformations, local transformations, pixel-wise processing, or a mixture of these operations. Global transformations are limited in enhancing local image regions.

Explorable Tone Mapping Operators [PDF]
2020 25th International Conference on Pattern Recognition (ICPR), 2021 Tone-mapping plays an essential role in high dynamic range (HDR) imaging. It aims to preserve visual information of HDR images in a medium with a limited dynamic range. Although many works have been proposed to provide tone-mapped results from HDR images, most of them can only perform tone-mapping in a single pre-designed way. However, the subjectivity

Unified implementation of global high dynamic range image tone-mapping algorithms
Mathematical Biosciences and Engineering, 2022 High dynamic range (HDR) images and video require tone-mapping for display on low dynamic range (LDR) screens. Many tone-mapping operators have been proposed to convert HDR content to LDR, but almost each has a different implementation structure and ...

Blind Tone-Mapped Image Quality Assessment Based on Regional Sparse Response and Aesthetics
Entropy, 2020 High dynamic range (HDR) images give a strong disposition to capture all parts of natural scene information due to their wider brightness range than traditional low dynamic range (LDR) images. However, to visualize HDR images on common LDR displays, tone
