Tone-Mapping Using Perceptual-Quantizer and Image Histogram
IEEE Access, 2020 A new tone-mapping algorithm is presented for visualization of high dynamic range (HDR) images on low dynamic range (LDR) displays. In the first step, the real-world pixel intensities of the HDR image are transformed to a perceptual domain using the ...

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 ...

Deep Tone-Mapping Operator Using Image Quality Assessment Inspired Semi-Supervised Learning
IEEE Access, 2021 Tone-mapping operator (TMO) is intended to convert high dynamic range (HDR) content into a lower dynamic range so that it can be displayed on a standard dynamic range (SDR) device. The tone-mapped result of HDR content is usually stored as SDR image. For

Tone mapping by interactive evolution [PDF]
Proceedings of the 11th Annual conference on Genetic and evolutionary computation, 2009 Tone mapping is a computational task of significance in the context of displaying high dynamic range images on low dynamic range devices. While a number of tone mapping algorithms have been proposed and are in common use, there is no single operator that yields optimal results under all conditions.

Human Visual System Model-Based Optimized Tone Mapping of High Dynamic Range Images
IEEE Access, 2021 High dynamic range (HDR) image and video technology can provide significant picture quality improvement over the standard dynamic range (SDR). However, when HDR content is represented on an SDR display, dynamic range compression may result in image ...

Journal of Low Power Electronics and Applications, 2013 Tone mapping algorithms are used to adapt captured wide dynamic range (WDR) scenes to the limited dynamic range of available display devices. Although there are several tone mapping algorithms available, most of them require manual tuning of their ...
