Photometric control system for the etching rate of thin dielectric films

open access: yesТехнологія та конструювання в електронній апаратурі, 2006
A methodology for photometric control of the etching rate of thin dielectric films is proposed, the essence of which consists in applying methods of double differentiation and time intervals to the signal of a photometric measuring device.

FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...

DOM: Dual Optical Mapping Integrating Sequence‐Specific Barcodes and A/T Density Profiles

open access: yesSmall Methods, EarlyView.
Dual Optical Mapping (DOM) combines sequence‐specific barcodes and an A/T profile to generate complementary genomic signatures along single DNA molecules. The integration of sparse and dense mapping information enables accurate and confident genome mapping, facilitating reliable localization of long DNA molecules in complex genomes, including the ...

VDNeRF: Vision‐Only Dynamic Neural Radiance Field for Urban Scenes

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Neural radiance fields (NeRFs) implicitly model continuous three‐dimensional scenes using a set of images with known camera poses, enabling the rendering of photorealistic novel views. However, existing NeRF‐based methods encounter challenges in applications such as autonomous driving and robotic perception, primarily due to the difficulty of ...

Boosting Embodied Visual Localisation Through Multi‐Granular Semantics and Multi‐Robot Consensus

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Achieving high accuracy and synergy remains extremely difficult for multi‐robot embodied visual localisation, which suffers from persistent real‐world challenges such as viewpoint ambiguity, appearance variation and dynamic occlusion. Conventional optimisation‐based methods often lead to incorrect feature matching without domain adaptation ...

Aggregating Spatial and Photometric Context for Photometric Stereo

open access: yes
Photometric stereo, a computer vision technique for estimating the 3D shape of objects through images captured under varying illumination conditions, has been a topic of research for nearly four decades. In its general formulation, photometric stereo is an ill-posed problem and requires robust prior knowledge of material reflectance properties, light ...

TMSA‐Net: Transformer‐Based Multi‐Scale Attention U‐Net for Flood Image Segmentation

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Flood detection is essential for real‐time applications, including disaster management, emergency response, and alerting people in flood zones. For successful flood detection, accurate flood region segmentation is essential. However, the flood region segmentation is challenging due to the complex background and occlusions with debris and the ...
