Highlights Analysis System (HAnS) for Low Dynamic Range to High Dynamic Range Conversion of Cinematic Low Dynamic Range Content

IEEE Access, 2021
We propose a novel and efficient algorithm for detection of specular reflections and light sources (highlights) in cinematic content. The detection of highlights is important for reconstructing them properly in the conversion of the low dynamic range ...

Multi-Bracket High Dynamic Range Imaging with Event Cameras [PDF]

2022 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2022
Modern high dynamic range (HDR) imaging pipelines align and fuse multiple low dynamic range (LDR) images captured at different exposure times. While these methods work well in static scenes, dynamic scenes remain a challenge since the LDR images still ...

FIREbox: Simulating galaxies at high dynamic range in a cosmological volume [PDF]

Monthly notices of the Royal Astronomical Society, 2022
We introduce a suite of cosmological volume simulations to study the evolution of galaxies as part of the Feedback in Realistic Environments project. FIREbox, the principal simulation of the present suite, provides a representative sample of galaxies (∼

High Speed and High Dynamic Range Video with an Event Camera [PDF]

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2019
Event cameras are novel sensors that report brightness changes in the form of a stream of asynchronous “events” instead of intensity frames. They offer significant advantages with respect to conventional cameras: high temporal resolution, high dynamic ...

Performance evaluation of dual-layer architectures for high dynamic range head mounted displays

Journal of Information Display, 2023
A high dynamic range head mounted display (HDR-HMD) using a dual-layer per-pixel modulation method was recently demonstrated where both the display and modulation layers spatially overlap with an equal pixel resolution and are well-aligned to each other ...

Dynamic Range Expansion Using Cumulative Histogram Learning for High Dynamic Range Image Generation

IEEE Access, 2020
In modern digital photographs, most images have low dynamic range (LDR) formats, which means that the range of light intensities from the darkest to the brightest is much lower than the range that can be perceived by the human eye.

Attention-Guided Network for Ghost-Free High Dynamic Range Imaging [PDF]

Computer Vision and Pattern Recognition, 2019
Ghosting artifacts caused by moving objects or misalignments is a key challenge in high dynamic range (HDR) imaging for dynamic scenes. Previous methods first register the input low dynamic range (LDR) images using optical flow before merging them, which
