Generating stereoscopic HDR images using HDR-LDR image pairs

ACM Transactions on Applied Perception, 2013
A number of novel imaging technologies have been gaining popularity over the past few years. Foremost among these are stereoscopy and high dynamic range (HDR) Imaging. While a large body of research has looked into each of these imaging technologies independently, very little work has attempted to combine them.

Objective HDR image quality assessment

Multimedia Tools and Applications, 2018
Although there is a lot of literature about generating HDR images, very limited research has been conducted on the issue of HDR image quality based on people’s feeling and preferences. The goal of this paper is to identify an objective quality measurement of an HDR image.

Image Quality Evaluation in Professional HDR/WCG Production Questions the Need for HDR Metrics [PDF]

IEEE Transactions on Image Processing, 2022
In the quality evaluation of high dynamic range and wide color gamut (HDR/WCG) images, a number of works have concluded that native HDR metrics, such as HDR visual difference predictor (HDR-VDP), HDR video quality metric (HDR-VQM), or convolutional ...

Image Brightness Quantification for HDR

2020 28th European Signal Processing Conference (EUSIPCO), 2021
Images’ brightness quantification is challenging due to the perceptual nature of brightness. In Standard Dynamic Range (SDR), the most common brightness quantification metrics are the Average Picture Level (APL) and the Frame Average Luminance Level (FALL).

LDR Image to HDR Image Mapping with Overexposure Preprocessing

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2013
International audienceDue to the growing popularity of High Dynamic Range (HDR) images and HDR displays, a large amount of existing Low Dynamic Range (LDR) images are required to be converted to HDR format to benefit HDR advantages, which give rise to ...

Rendering HDR Images

Color and Imaging Conference, 2003
Color imaging systems are continuously improving, and have now improved to the point of capturing high dynamic range scenes. Unfortunately most commercially available color display devices, such as CRTs and LCDs, are limited in their dynamic range. It is necessary to tone-map, or render, the high dynamic range images in order to display them onto a ...

Radiometric calibration for HDR imaging

2015 IEEE International Conference on Image Processing (ICIP), 2015
In this paper we present a method to estimate the radiance map and camera response function for high dynamic range (HDR) imaging which is devoid of free parameters and can reliably recover HDR images with as few as two low-dynamic range (LDR) views acquired at different exposures.

An Application of HDR in Medical Imaging

2016
We describe a solution aimed at overcoming dynamic range problems in the visualization of medical images. We first analyze the specific requirements for a high dynamic range (HDR) display that should operate in the medical (diagnostic) context, and the procedures that are followed in a laboratory of the US Food and Drug Administration to evaluate such ...

HDR Image Compression with Convolutional Autoencoder

2020 IEEE International Conference on Visual Communications and Image Processing (VCIP), 2020
As one of the next-generation multimedia technology, high dynamic range (HDR) imaging technology has been widely applied. Due to its wider color range, HDR image brings greater compression and storage burden compared with traditional LDR image. To solve this problem, in this paper, a two-layer HDR image compression framework based on convolutional ...

Single-Image HDR Reconstruction Assisted Ghost Suppression and Detail Preservation Network for Multi-Exposure HDR Imaging

IEEE Transactions on Computational Imaging
The reconstruction of high dynamic range (HDR) images from multi-exposure low dynamic range (LDR) images in dynamic scenes presents significant challenges, especially in preserving and restoring information in oversaturated regions and avoiding ghosting ...
