In this paper we model the process of temporal adaptation of the human visual system to varying luminance conditions. An eye tracker is used to capture the location of an observer’s gaze in a high dynamic range image displayed on the screen. We apply a novel technique of eye tracker data filtering to avoid flickering caused by incorrect gaze estimation.

Content-adaptive inverse tone mapping
2012 Visual Communications and Image Processing, 2012Tone mapping is an important technique used for displaying high dynamic range (HDR) content on low dynamic range (LDR) devices. On the other hand, inverse tone mapping enables LDR content to appear with an HDR effect on HDR displays. The existing inverse tone mapping algorithms usually focus on enhancing the luminance in over-exposed regions with less (

Matching by Monotonic Tone Mapping
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2018In this paper, a novel dissimilarity measure called Matching by Monotonic Tone Mapping (MMTM) is proposed. The MMTM technique allows matching under non-linear monotonic tone mappings and can be computed efficiently when the tone mappings are approximated by piecewise constant or piecewise linear functions.

Perception-inspired tone mapping
2007The display of high dynamic range images and video requires a tonemapping algorithm to depict their original appearance on existing display devices whose capabilities in terms of dynamic range are insufficient. The insightful application of knowledge about human visual system can assure high fidelity of depiction in such an algorithm.

Tone mapping for video gaming applications
2018 IEEE International Conference on Consumer Electronics (ICCE), 2018Due to the increasing interest in physical-based rendering in High Dynamic Range (HDR) in game development and the lack of commercial HDR displays, tone mapping the HDR game content to match the capabilities of Standard Dynamic Range (SDR) displays is currently a topic of high importance.

Modeling a Generic Tone‐mapping Operator
Computer Graphics Forum, 2008AbstractAlthough several new tone‐mapping operators are proposed each year, there is no reliable method to validate their performance or to tell how different they are from one another. In order to analyze and understand the behavior of tone‐mapping operators, we model their mechanisms by fitting a generic operator to an HDR image and its tone‐mapped ...

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.

Learning Tone Mapping Function for Dehazing
Cognitive Computation, 2016The existence of haze greatly degrades the image quality and hence decreases the cognition performance of a vision system. Therefore, it is crucial to remove haze from images. Instead of formulating dehazing as an image rest-oration or mathematical inversion problem, we, in this paper, conduct dehazing by learning a proper transformation function (i. e.

A reality check for tone-mapping operators
ACM Transactions on Applied Perception, 2006A large number of high-quality tone-mapping operators is currently available. In addition to inherent practical value, comparing their performance is necessary to further advance the field and can provide better understanding of visual realism. In this paper, we show that it becomes very difficult to meaningfully judge relative performance of modern ...

Deep Video Inverse Tone Mapping
2019 IEEE Fifth International Conference on Multimedia Big Data (BigMM), 2019Inverse tone mapping is an important topic in High Dynamic Range technology. Recent years, deep learning based image inverse tone mapping methods have been extensively studied and perform better than classical inverse tone mapping methods. However, these methods consider the inverse tone mapping problem as a domain transformation problem from LDR ...
