Learning Preferential Perceptual Exposure for HDR Displays
IEEE Access, 2019 High dynamic range (HDR) displays are capable of displaying a wider dynamic range of values than conventional displays. As HDR content becomes more ubiquitous, the use of these displays is likely to accelerate.

High-Dynamic-Range CT Reconstruction Based on Varying Tube-Voltage Imaging. [PDF]
PLoS ONE, 2015 For complicated structural components characterized by wide X-ray attenuation ranges, the conventional computed tomography (CT) imaging using a single tube-voltage at each rotation angle cannot obtain all structural information.

RADIANCE DOMAIN COMPOSITING FOR HIGH DYNAMIC RANGE IMAGING [PDF]
ICTACT Journal on Image and Video Processing, 2013 High dynamic range imaging aims at creating an image with a range of intensity variations larger than the range supported by a camera sensor. Most commonly used methods combine multiple exposure low dynamic range (LDR) images, to obtain the high dynamic ...

High Dynamic Range (HDR) images of radiographies: modern digital replacement of negatoscopes?
Estudos de Conservação e Restauro, 2013 With this paper we are presenting a new promising approach to digitalization of radiographic image in film, using common photographic cameras as device to digitalize with different levels of exposure (allowing, in some cases, to read information from the darker/denser areas of the image) and combining those images with the new technique of High Dynamic

Real time delivery of HDR video [PDF]
, 2014 High Dynamic Range (HDR) video provides a step change in viewing experience, for example the ability to clearly see the football when it is kicked from the shadow of the stadium into sunshine. To achieve the full potential of HDR video, socalled trueHDR,

Backward Compatible Object Detection Using HDR Image Content
IEEE Access, 2020 Convolution Neural Network (CNN)-based object detection models have achieved unprecedented accuracy in challenging detection tasks. However, existing detection models (detection heads) trained on 8-bits/pixel/channel low dynamic range (LDR) images are ...

High dynamic range optical coherence tomography angiography (HDR-OCTA)
Biomedical Optics Express, 2019 The dynamic range of current optical coherence tomography (OCT) angiography (OCTA) images is limited by the fixed scanning intervals. High speed OCT devices introduce the possibility of extending the flow signal dynamic range. In this study, we created a novel scanning pattern for achieving high dynamic range (HDR)-OCTA with a superior scanning ...

Learning High Dynamic Range from Outdoor Panoramas
, 2017 Outdoor lighting has extremely high dynamic range. This makes the process of capturing outdoor environment maps notoriously challenging since special equipment must be used. In this work, we propose an alternative approach. We first capture lighting with
