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 ...

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

High-throughput high-dynamic range imaging by spatiotemporally structured illumination

open access: yesAPL Photonics, 2022
Recent advances in biochemistry and optics have enabled observation of the faintest signals from even single molecules. However, although biological samples can have varying degrees of fluorescence expression ranging from a single to thousands of ...

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

open access: yesIEEE 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 ...

High-Dynamic-Range CT Reconstruction Based on Varying Tube-Voltage Imaging. [PDF]

open access: yesPLoS 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.

Stereo Vision-Based High Dynamic Range Imaging Using Differently-Exposed Image Pair

open access: yesSensors, 2017
In this paper, a high dynamic range (HDR) imaging method based on the stereo vision system is presented. The proposed method uses differently exposed low dynamic range (LDR) images captured from a stereo camera.

Multiple-Exposure Image Fusion for HDR Image Synthesis Using Learned Analysis Transformations

open access: yesJournal of Imaging, 2019
Modern imaging applications have increased the demand for High-Definition Range (HDR) imaging. Nonetheless, HDR imaging is not easily available with low-cost imaging sensors, since their dynamic range is rather limited.

Backward Compatible Object Detection Using HDR Image Content

open access: yesIEEE 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 ...

HDR Imaging Based on Low-rank Matrix Completion and Total Variation Constraint [PDF]

open access: yesJisuanji gongcheng, 2019
The High Dynamic Range(HDR) imaging method based on Low-rank Matrix Completion(LRMC) removes the ghost image of the moving target in the resulting image by restoring the background information of the moving target occlusion.However,since the model ...
