High Dynamic Range Fluorescence Imaging [PDF]

open access: yesIEEE Journal of Selected Topics in Quantum Electronics, 2019
Fluorescence acquisition and image display over a high dynamic range is highly desirable. However, the limited dynamic range of current photodetectors and imaging CCDs impose a limit on the fluorescence intensities that can be simultaneously captured during a single image acquisition.

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

open access: yesIEEE 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.

Foreword – High dynamic range imaging [PDF]

open access: yesComputers & 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 ...

Resolution Enhancement in Coherent Diffraction Imaging Using High Dynamic Range Image

open access: yesPhotonics, 2021
In a coherent diffraction imaging (CDI) system, the information of the sample is retrieved from the diffraction patterns recorded by the image sensor via multiple iterations.

Visualization of high dynamic range images [PDF]

open access: yesProceedings. 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.

Single Exposure High Dynamic Range Image Reconstruction Based on Deep Dual-Branch Network

open access: yesIEEE Access, 2021
In this article, we relate the operation of single-frame-based high dynamic range (HDR) image reconstruction to the following two tasks: 1) highlight suppression in over-exposed areas and 2) noise elimination in under-exposed areas.

Reconstructing a High Dynamic Range Image With a Deeply Unsupervised Fusion Model

open access: yesIEEE Photonics Journal, 2021
To well record a high-dynamic-range (HDR) natural scene, multi-exposure images fusion is an affordable and convenient option, which is a hotspot in the field of HDR imaging. In this paper, we propose a deep learning-based method to address multi-exposure

Supervised Image Segmentation for High Dynamic Range Imaging

open access: yes2023 IEEE International Conference on Acoustics, Speech, and Signal Processing Workshops (ICASSPW), 2023
Regular cameras and cell phones are able to capture limited luminosity. Thus, in terms of quality, most of the produced images from such devices are not similar to the real world. They are overly dark or too bright, and the details are not perfectly visible. Various methods, which fall under the name of High Dynamic Range (HDR) Imaging, can be utilised
