Model for High Dynamic Range Imaging System Using Hybrid Feature Based Exposure Fusion

open access: yesJournal of Intelligent Systems, 2020
The luminous value is high for many natural scenes, which causes loss of information and occurs in dark images. The High Dynamic Range (HDR) technique captures the same objects or scene for multiple times in different exposure and produces the images ...

Peptide Triazole Thiol Irreversibly Inactivates Metastable HIV-1 Env by Accessing Conformational Triggers Intrinsic to Virus–Cell Entry

open access: yesMicroorganisms, 2021
KR13, a peptide triazole thiol previously established to inhibit HIV-1 infection and cause virus lysis, was evaluated by flow cytometry against JRFL Env-presenting cells to characterize induced Env and membrane transformations leading to irreversible ...

Fusion of secretory vesicles isolated from rat liver [PDF]

open access: yes, 1978
Secretory vesicles isolated from rat liver were found to fuse after exposure to Ca2+. Vescle fusion is characterized by the occurrence of twinned vesicles with a continuous cleavage plane between two vesicles in freeze-fracture electron microscopy.

Perceptual Multi-Exposure Fusion

open access: yesCoRR, 2022
As an ever-increasing demand for high dynamic range (HDR) scene shooting, multi-exposure image fusion (MEF) technology has abounded. In recent years, multi-scale exposure fusion approaches based on detail-enhancement have led the way for improvement in highlight and shadow details.

Exposure Bracketing Techniques for Camera Document Image Enhancement

open access: yesApplied Sciences, 2019
Capturing document images using digital cameras in uneven lighting conditions is challenging, leading to poorly captured images, which hinders the processing that follows, such as Optical Character Recognition (OCR).

Multi‐exposure image fusion based on feature evaluation with adaptive factor

open access: yesIET Image Processing, 2021
The authors present a new multi‐exposure images fusion method based on feature evaluation with adaptive factor. It is noticed the existing multi‐exposure fusion algorithm is not well adapted to the input images, which are overall bright or dark, the ...

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.
