High performance γ-ray imager using dual anti-mask method for the investigation of high-energy nuclear materials

open access: yesNuclear Engineering and Technology, 2021
As the γ-ray energy increases, a reconstructed image becomes noisy and blurred due to the penetration of the γ-ray through the coded mask. Therefore, the thickness of the coded mask was increased for high energy regions, resulting in severely decreased ...

Sidewall patterning of organic–inorganic multilayer thin film encapsulation by adhesion lithography

open access: yesScientific Reports, 2023
A simple sidewall patterning process for organic–inorganic multilayer thin-film encapsulation (TFE) has been proposed and demonstrated. An Al2O3 thin film grown by atomic layer deposition (ALD) was patterned by adhesion lithography using the difference ...

Shadow Detection and Compensation from Remote Sensing Images under Complex Urban Conditions

open access: yesRemote Sensing, 2021
Due to the block of high-rise objects and the influence of the sun’s altitude and azimuth, shadows are inevitably formed in remote sensing images particularly in urban areas, which causes missing information in the shadow region.

Shadow Compensation from UAV Images Based on Texture-Preserving Local Color Transfer

open access: yesRemote Sensing, 2022
The lack of color information and texture information in the shadow region seriously affect the recognition and interpretation of remote sensing image information. The commonly used methods focus on the restoration of texture information, but it is often

Shadow Removal from UAV Images Based on Color and Texture Equalization Compensation of Local Homogeneous Regions

open access: yesRemote Sensing, 2022
Due to imaging and lighting directions, shadows are inevitably formed in unmanned aerial vehicle (UAV) images. This causes shadowed regions with missed and occluded information, such as color and texture details.
