iTM-Net: Deep Inverse Tone Mapping Using Novel Loss Function Considering Tone Mapping Operator
IEEE Access, 2019 In this paper, we propose a novel inverse tone mapping network, called “iTM-Net.” For training iTM-Net, we also propose a novel loss function that considers the non-linear relation between low dynamic range (LDR) and high dynamic range (HDR)

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.

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

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.

TONE COMPRESSION ALGORITHM FOR HIGH DYNAMIC RANGE MEDICAL IMAGES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 We propose here an HDR compression method for medical images based on a windowing operator, an adaptive tone mapping operator, and the probabilistic normal-gamma model.

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.

Layer Decomposition based Local Tone Mapping Operator
International Journal of Emerging Research in Engineering, Science, and Management, 2022 Dynamic range of an image directly defines the number of levels it can accommodate in an image. In general, a dynamic range of 256 is in use. Defining dynamic range of an image need to be done by considering the display unit on which the image will be ...

Fully-automatic inverse tone mapping algorithm based on dynamic mid-level tone mapping [PDF]
, 2020 High Dynamic Range (HDR) displays can show images with higher color contrast levels and peak luminosities than the common Low Dynamic Range (LDR) displays. However, most existing video content is recorded and/or graded in LDR format.
