Color correction for tone mapping

Computer Graphics Forum, 2009
AbstractTone mapping algorithms offer sophisticated methods for mapping a real‐world luminance range to the luminance range of the output medium but they often cause changes in color appearance. In this work we conduct a series of subjective appearance matching experiments to measure the change in image colorfulness after contrast compression and ...

GaussHDR: High Dynamic Range Gaussian Splatting via Learning Unified 3D and 2D Local Tone Mapping

Computer Vision and Pattern Recognition
High dynamic range (HDR) novel view synthesis (NVS) aims to reconstruct HDR scenes by leveraging multi-view low dynamic range (LDR) images captured at different exposure levels. Current training paradigms with 3D tone mapping often result in unstable HDR

Tone-Mapped Mean-Shift Based Environment Map Sampling

IEEE Transactions on Visualization and Computer Graphics, 2016
In this paper, we present a novel approach for environment map sampling, which is an effective and pragmatic technique to reduce the computational cost of realistic rendering and get plausible rendering images. The proposed approach exploits the advantage of adaptive mean-shift image clustering with aid of tone-mapping, yielding oversegmented strata ...

LTM-NeRF: Embedding 3D Local Tone Mapping in HDR Neural Radiance Field

IEEE Transactions on Pattern Analysis and Machine Intelligence
Recent advances in Neural Radiance Fields (NeRF) have provided a new geometric primitive for novel view synthesis. High Dynamic Range NeRF (HDR NeRF) can render novel views with a higher dynamic range.

Optimal Tone Mapping

Linguistic Inquiry, 2003
Traditional autosegmental accounts of tone mapping invoke three independent factors: morphological category, tone quality, and a phonological directionality parameter. This article argues that the evidence for phonological directionality must be reconsidered.

Semantic Aware Diffusion Inverse Tone Mapping

Journal of Physics: Conference Series
Capturing the full luminance range of real-world scenes exceeds the capabilities of most digital cameras, often resulting in detail loss, particularly in bright regions.

Interactive Tone Mapping

2000
Tone mapping and visual adaptation are crucial for the generation of static, photorealistic images. A largely unexplored problem is the simulation of adaptation and its changes over time on the visual appearance of a scene. These changes are important in interactive applications, including walkthroughs or games, where effects such as dazzling, slow ...

Selective local tone mapping

2013 IEEE International Conference on Image Processing, 2013
When preparing high dynamic range images (HDR) for display on standard monitors, it is often necessary to make a choice between global and local tone mapping. While the former is simple and efficient, it may fail to reproduce details in high contrast image regions. Although, the latter can better reproduce details in such regions, it often comes at the
