Perceptual Tone Mapping Model for High Dynamic Range Imaging
IEEE Access, 2023 One of the key challenges in tone mapping is to preserve the perceptual quality of high dynamic range (HDR) images when mapping them to standard dynamic range (SDR) displays.

Characterization for High Dynamic Range Imaging [PDF]
Computer Graphics Forum, 2008 AbstractIn this paper we present a new practical camera characterization technique to improve color accuracy in high dynamic range (HDR) imaging. Camera characterization refers to the process of mapping device‐dependent signals, such as digital camera RAW images, into a well‐defined color space.

Foreword – High dynamic range imaging [PDF]
Computers & Graphics, 2013 High Dynamic Range (HDR) imagery is a step-change in imaging technology that is not limited to the 8-bits per pixel for each color channel that traditional or low-dynamic range digital images have been constrained to. These restrictions have meant that the current and relatively novel imaging technologies including stereoscopic, HD and ultraHD imaging ...

Pyramidal Feature Adjustment Networks for High Dynamic Range Imaging of Dynamic Scenes
IEEE Access, 2023 Multi-exposure high dynamic range (HDR) imaging aims to generate an HDR image from multiple low dynamic range (LDR) images. There are two main challenges in this task; camera and object motions causing ghost artifacts and over/under-exposure areas having

Single-Shot High Dynamic Range Imaging via Multiscale Convolutional Neural Network
IEEE Access, 2021 We propose a single-shot high dynamic range (HDR) imaging algorithm with row-wise varying exposures in a single raw image based on a deep convolutional neural network (CNN). We first convert a raw Bayer input image into a radiance map by calibrating rows

Exposure-Structure Blending Network for High Dynamic Range Imaging of Dynamic Scenes
IEEE Access, 2020 This paper presents a deep end-to-end network for high dynamic range (HDR) imaging of dynamic scenes with background and foreground motions. Generating an HDR image from a sequence of multi-exposure images is a challenging process when the images have ...

Visualization of high dynamic range images [PDF]
Proceedings. International Conference on Image Processing, 2003 A novel paradigm for information visualization in high dynamic range images is presented in this paper. These images, real or synthetic, have luminance with typical ranges many orders of magnitude higher than that of standard output/viewing devices, thereby requiring some processing for their visualization.
