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

IEEE 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

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

IEEE 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.

Characterization for high dynamic range imaging [PDF]

, 2008
In this paper we present a new practical camera characterization technique to improve color accuracy in high dynamic range (HDR) imaging. Camera characterization refers to the process of mapping device-dependent signals, such as digital camera RAW images,

High Dynamic Range and Super-Resolution Imaging From a Single Image

IEEE Access, 2018
This paper presents an algorithm for high dynamic range (HDR) and super-resolution (SR) imaging from a single image. First, we propose a new single image HDR imaging (HDRI) method based on the Retinex approach and exploit a recent single image SR method ...
