Training Neural Networks on RAW and HDR Images for Restoration Tasks

no code implementations6 Dec 2023 Lei Luo, ALEXANDRE CHAPIRO, Xiaoyu Xiang, Yuchen Fan, Rakesh Ranjan, Rafal Mantiuk

Our results indicate that neural networks train significantly better on HDR and RAW images represented in display-encoded color spaces, which offer better perceptual uniformity than linear spaces.

Stereoscopic Depth Perception Through Foliage

1 code implementation24 Oct 2023 Robert Kerschner, Rakesh John Amala Arokia Nathan, Rafal Mantiuk, Oliver Bimber

The same was true with stereoscopic video because of the occlusions caused by foliage.

Perceptual Quality Assessment of NeRF and Neural View Synthesis Methods for Front-Facing Views

no code implementations24 Mar 2023 Hanxue Liang, Tianhao Wu, Param Hanji, Francesco Banterle, Hongyun Gao, Rafal Mantiuk, Cengiz Oztireli

We measured the quality of videos synthesized by several NVS methods in a well-controlled perceptual quality assessment experiment as well as with many existing state-of-the-art image/video quality metrics.

G-SemTMO: Tone Mapping with a Trainable Semantic Graph

no code implementations30 Aug 2022 Abhishek Goswami, Erwan Bernard, Wolf Hauser, Frederic Dufaux, Rafal Mantiuk

In this work, we draw inspiration from an expert photographer's approach and present a Graph-based Semantic-aware Tone Mapping Operator, G-SemTMO.

Active Sampling for Pairwise Comparisons via Approximate Message Passing and Information Gain Maximization

1 code implementation12 Apr 2020 Aliaksei Mikhailiuk, Clifford Wilmot, Maria Perez-Ortiz, Dingcheng Yue, Rafal Mantiuk

In this paper we propose ASAP, an active sampling algorithm based on approximate message passing and expected information gain maximization.

Dynamic Range Independent Image Quality Assessment

no code implementations SIGGRAPH 2008 Tunç O. Aydın, Rafal Mantiuk, Karol Myszkowski, Hans-Peter Seidel

Current quality assessment metrics are not suitable for this task, as they assume that both reference and test images have the same dynamic range.
