Evaluation of High Dynamic Range Imaging Methods for Luminance Measurements [PDF]

open access: yesJournal of Imaging
Imaging luminance measurement is increasingly used in lighting applications, but the limited dynamic range of camera sensors requires using high dynamic range (HDR) imaging methods for evaluating scenes with large luminance contrasts.

Ghost-Free HDR Imaging in Dynamic Scenes via High–Low-Frequency Decomposition [PDF]

open access: yesSensors
Generating high-quality high-dynamic-range (HDR) images in dynamic scenes remains a challenging task. Recently, Transformers have been introduced into HDR imaging and have demonstrated superior performance over traditional convolutional neural networks ...

An HDR imaging method with DTDI technology for push-broom cameras

open access: yesPhotonic Sensors, 2017
Conventionally, high dynamic-range (HDR) imaging is based on taking two or more pictures of the same scene with different exposure. However, due to a high-speed relative motion between the camera and the scene, it is hard for this technique to be applied

HCNet: Multi-Exposure High-Dynamic-Range Reconstruction Network for Coded Aperture Snapshot Spectral Imaging [PDF]

open access: yesSensors
Coded Aperture Snapshot Spectral Imaging (CASSI) is a rapid hyperspectral imaging technique with broad application prospects. Due to limitations in three-dimensional compressed data acquisition modes and hardware constraints, the compressed measurements ...

Perceived dynamic range of HDR images [PDF]

open access: yes2016 Eighth International Conference on Quality of Multimedia Experience (QoMEX), 2016
Although high dynamic range (HDR) imaging has gained great popularity and acceptance in both the scientific and commercial domains, the relationship between perceptually accurate, content-independent dynamic range and objective measures has not been ...

Visual glare limits of HDR displays in medical imaging

open access: yesIET Computer Vision, 2018
Emerging display technologies are proposing monitors for medical imaging with an extended dynamic range of luminance. Those devices offer the opportunity to extend the range of visual information displayed, but the limits of the human visual system (HVS)

HDR-GAN: HDR Image Reconstruction From Multi-Exposed LDR Images With Large Motions [PDF]

open access: yesIEEE Transactions on Image Processing, 2021
Synthesizing high dynamic range (HDR) images from multiple low-dynamic range (LDR) exposures in dynamic scenes is challenging. There are two major problems caused by the large motions of foreground objects. One is the severe misalignment among the LDR images. The other is the missing content due to the over-/under-saturated regions caused by the moving

Effective despeckling of HDR images [PDF]

open access: yesSIGGRAPH Asia 2011 Sketches, 2011
High Dynamic Range (HDR) images are common in computer graphics. In these images, speckles can appear for various reasons, such as high variance for Monte-Carlo-based rendering engines. These speckles are responsible for large artefacts if non-robust post-processing methods are used, such as tonemapping operators relying on a maximal or average ...

First Demonstration of Calibrated Color Imaging by the CAOS Camera

open access: yesPhotonics, 2021
The Coded Access Optical Sensor (CAOS) camera is a novel, single unit, full spectrum (UV to short-wave IR bands), linear, high dynamic range (HDR) camera.

Extending Effective Dynamic Range of Hyperspectral Line Cameras for Short Wave Infrared Imaging

open access: yesSensors, 2022
In this work, a multi-exposure method is proposed to increase the dynamic range (DR) of hyperspectral imaging using an InGaAs-based short-wave infrared (SWIR) hyperspectral line camera.
