After analysis of range (LDR) images of the same scene taken under differentthese techniques we had concluded that fast tone-mapping exposure intervals. Several works try to select the mostalgorithm is most computationally efficient and easy but appropriate LDR images to generate the HDR image ...
local tone mappingA new method of dynamic backlight control, based on Local Tone Mapping, which avoids traditional dynamic and static artifacts, is introduced and is compared quantitatively with currently deployed CABC approaches. This paper also describes a methodology, based on user studies, for ...
To conclude, in this post I came back to the topic of localized tonemapping, its general ideas and have described the “exposure fusion” algorithm with a simple, GPU friendly implementation – suitable for asimple WebGL demo(I release it to public domain, feel free to use or modify as m...
Tone mapping (TM) algorithms reproduce the high dynamic range (HDR) images on low dynamic range (LDR) display devices such as monitors or printers. In this paper, we propose a local TM algorithm, in which the HDR input is segmented using the K-means algorithm and a display gamma parameter...
We present a fast global and locally adaptive tone mapping algorithm and its FPGA implementation. The specially designed tone mapping function, which is based on local histogram equalization, controls global and local characteristics individually. In contrast to other tonemap operators, our algorithm man...
最近在做低照度图像恢复时,发现了一个充满知识的 github 工程:点这里,里面有一篇论文,《Adaptive Local Tone Mapping Based on Retinex for High Dynamic Range Images》,它结合传统的 Retinex 技术提出了全局自适应和局部自适应的 HDR 实现过程,...
III. PROPOSED TONE MAPPING BASED ON RETINEX In Section 2, we described the characteristics and drawbacks of the retinex algorithms. These drawbacks are overcome by introducing a new method. In our algorithm, luminance values are obtained from input HDR images and processed. First, we apply...
Other artifacts that can be acceptable include contrast reduction. The tone mapping algorithm can capture the details of a high bit-depth (e.g. 12 or 16 bit) image into a single 8-bit image, so more these details can be seen (such as the area marked with the circles502,602in FIGS. ...
In low frequency regions, we employ global tone mapping to save computational resources without degrading quality. Our algorithm is most suitable for tone mapping operators (TMOs) that utilize the concept of local adaptation luminances. 展开 关键词:...
