image quality assessmenttone mapping operatorHigh dynamic range (HDR) images allow us to capture greater luminance levels between its brightest and darkest regions than standard or low dynamic range (LDR) images. A common problem that is often encountered in practice is concerned about the ...
Durand's algorithm 杜兰德算法 该算法的主要思想是将辐射图像分解为两层:编码大规模变化的基础层和细节层。仅降低基础层的对比度,从而在色调映射图像中保留细节。该算法也可以用 3 个步骤来说明: 通过对辐射图像的对数应用边缘保留滤波器(即双边滤波器)来获得基础层。使用辐射图像对数的原因在莱因哈德算法的第一步...

In proposed algorithm, an RGB image is converted into an HSV image. The V component provides intensity information of images and it can be easily used to estimate the global and local illuminants. The new algorithm introduces an adaptive gamma correction method as a function of local illuminant...

Still, most existing legacy video content is either recorded or mastered in a lower standard dynamic range (SDR) quality. To show standard dynamic range content on High Dynamic Range displays, the content needs to be upconverted using a so-called ‘inverse tone mapping’ algorithm. You may also...
Our global tone mapping operator HALEQ works very fast and well reproduces global contrast for high dynamic range images, which overcomes some drawbacks of well-known histogram adjustment tone mapping operator [8] and provides a better base for our local tone mapping algorithm. However, global ...

FIG. 3C is a diagram of curves for static tone-mapping. If static tone-mapping is used, the tone-mapping algorithm can be based on the maximum panel luminance PL of the display panel or the maxCLL parameter of the input HDR video signal. For example, if the tone-mapping algorithm is ba...
