Tone mappingTone mapping algorithms reproduce high dynamic range (HDR) images on low dynamic range images in the standard display devices such as LCD, CRT, projectors, and printers. In this paper, we propose a statistical clustering-based tone mapping technique that would be able to adapt the ...
Tone mapping algorithms are used in image processing that reduces the range of high dynamic range (HDR) image to be displayed on low dynamic range (LDR) devices. The retinex method is one of the tone mapping algorithms to provide dynamic range compression, color constancy, and color rendition....
Tone mapping algorithms should be informed by accurate color appearance models (CAM) in order that the perceptual fidelity of the rendering is maintained by the tone mapping transformations. Current tone mapping techniques, however, suffer from a lack of good color appearance models for mesopic ...
Non-realtime inverse tone-mapping algorithms require high computation time but usually come with improved output quality. Such solutions are often part of a wider set of color grading and mastering functionalities and hence offer flexible parametric color processing capabilities with manual adjustment capa...
However, it is still hard to find a computational model which can determine the superiority of the tone mapping algorithms. Thus, a better way of understanding the superiority of the tone mapping algorithms is to use human observers and psychophysical experimentation to evaluate their performance. ...
correction is applied to further refine color accuracy and eliminate any color shifting that can occur after dynamic range compression and color space compression. This process distinguishes it from many existing tone mapping algorithms that often reduce image sharpness as a side effect of color ...
Tone Mapping Survey GlobalToneMappingAlgorithms 全局色调映射算法(也称为“色调重现曲线”)在空间上是不变的,也就是说,它们对输入图像中的所有像素都应用相同的功能[115-119]。 这导致针对特定输入像素值的一个且只有一个输出值,而不管其附近的像素如何。 图3.3显示了一个通用管道,可用于实现图3.2(a)所示的全...
Among other, pyramid-based tone mapping algorithms are well known to enhance the dynamic range of images. Therefore, the image data is deconstructed into a plurality of N levels or layers. The first level, in a Gaussian-pyramid algorithm for example, is a Gaussian-filtered image of the initia...
