TLDR
Novel contributions of this work include an edge-preserving smoother for the extraction of the visual adaptation level which avoids the formation of halo artifacts in the resulting image and a technique for contrast mapping which improves the visibility of the image details.Abstract:
We present a new dynamic range compression method for the reproduction of high dynamic range digital images on conventional display devices. The proposed technique is computationally efficient and easily adjustable with few parameters. Novel contributions of this work include an edge-preserving smoother for the extraction of the visual adaptation level which avoids the formation of halo artifacts in the resulting image and a technique for contrast mapping which improves the visibility of the image details. The algorithm is finally evaluated by means of an objective measure proving its effectiveness.read more

Color Grading Apparatus and Methods
TL;DR: In this article, a method for color grading input video data for display on a target display comprises obtaining target display metadata indicative of a capability of the target display, obtaining input data metadata indicating the image characteristics of the input data and automatically determining initial values for parameters of a parameterized sigmoidal transfer function.

TL;DR: An experiment on lighting perception using a series of LED lighting conditions in a real space and a virtual representation of those conditions captured using a 360° high-dynamic-range camera and presented on an HTC Vive Pro HMD shows ratings of visual comfort, pleasantness, evenness, contrast and glare are similar.

Tone mapping based on fast image decomposition and multi-layer fusion
TL;DR: The authors propose a novel tone mapping algorithm based on fast image decomposition and multi-layer fusion that could bring better brightness, contrast, and visibility with less halo effect than other state-of-the-art methods both qualitatively and quantitatively in most cases.

A visibility matching tone reproduction operator for high dynamic range scenes
TL;DR: A tone reproduction operator is presented that preserves visibility in high dynamic range scenes and introduces a new histogram adjustment technique, based on the population of local adaptation luminances in a scene, that incorporates models for human contrast sensitivity, glare, spatial acuity, and color sensitivity.
