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 ...

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 ...

Multi-exposure Image Fusion using Patch-based Component Decomposition
International Journal of Emerging Research in Engineering, Science, and Management, 2022 Multi exposure image fusion is always a challenge in task in image processing. The multiple images with the different image content, when mixed using a fusion formula generate different effects. One of the most prominent effects is ghosting effect. Ghost

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 ...

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.

Visible and Near-Infrared Image Acquisition and Fusion for Night Surveillance
Chemosensors, 2021 Image fusion combines images with different information to create a single, information-rich image. The process may either involve synthesizing images using multiple exposures of the same scene, such as exposure fusion, or synthesizing images of ...

Hierarchical tone mapping based on image colour appearance model
IET Computer Vision, 2014 To solve the problem of low efficiency and poor effect of the current tone mapping methods for the high dynamic range images, the authors propose a hierarchical tone mapping algorithm based on colour appearance model. The discrete Gaussian kernel is used
