Calculating shadowing and masking on a rough surface
Heliyon, 2023 Existing research has confirmed that light attenuation has an intrinsic effect on light reflection from rough surfaces. In this study, a technique is developed to solve the shadowing and masking problems of visual representation on a rough surface.

Shadow detection from images using fuzzy logic and PCPerturNet
IET Image Processing, 2021 Shadow detection is a challenging and essential task for interpreting the scene. Regardless of encouraging findings from current Deep Learning (DL) approaches used for shadow detection, the methods are also dealing with inconsistent situations where the ...

Free-standing silicon shadow masks for transmon qubit fabrication
AIP Advances, 2020 Nanofabrication techniques for superconducting qubits rely on resist-based masks patterned by electron-beam or optical lithography. We have developed an alternative nanofabrication technique based on free-standing silicon shadow masks fabricated from ...

Máscaras mecânicas de sombra por eletrocorrosão para dispositivos eletro-ópticos
Química Nova, 2014 Shadow masks are used in manufacturing processes for electro-optic devices to transfer patterns with different shapes and dimensions. For fabrication of organic based devices, shadow masks should be made of materials stable against organic solvents, high

Advanced photomask fabrication by e-beam lithography for mask aligner applications
, 2022 Paper 1003204Photomasks contain geometric information that will be transferred to substrates or pre-structured surfaces. Conventional mask aligner lithography in the sense of shadow printing of the photomask suffers from limited achievable resolution ...

TS-DeShadowNet: A Two-Stage Remote Sensing Image Shadow Removal Method
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingShadow removal for remote sensing images is a challenging task. Mask-based methods require prohibitively expensive pixel-level shadow mask annotation, while mask-free methods suffer from a domain gap between rigorously consistent paired shadow and shadow-

Direct 3D printed shadow mask on Silicon
, 2016 A 3D printed shadow mask method is presented. The 3D printer prints ABS plastic directly on the wafer, thus avoiding gaps between the wafer and the shadow mask, and deformation during the process.

Throwaway Shadows Using Parallel Encoders Generative Adversarial Network
Applied Sciences, 2022 Face photographs taken on a bright sunny day or in floodlight contain unnecessary shadows of objects on the face. Most previous works deal with removing shadow from scene images and struggle with doing so for facial images.
