A BEMD-Based Quaternion Filtering Approach Sharp-to-Soft Kernel CT Image Conversion
Mahmoud Nasr, Jan K. Argasinski, Krzysztof Brzostowski +1
The quality of computed tomography (CT) images is significantly affected by the selection of reconstruction kernels: sharp kernels improve spatial resolution but increase noise, wh…
Decomposition-Guided Curvelet Thresholding for Sharp-to-Soft CT Kernel Conversion
Mahmoud Nasr, Jan K. Argasinski, Krzysztof Brzostowski +1
Image denoising is a crucial task in image processing, focused on improving image quality by minimizing noise while maintaining essential structural elements. This study presents a…
LEON: Location Embeddings from OSM Neighborhoods via Hexagonal Graph Masked Autoencoders
Szymon Soltysiak, Radoslaw Malek, Jedrzej Kusnierz +3
Geographic information systems increasingly rely on sophisticated spatial representation learning techniques to extract meaningful patterns from complex geospatial data. This paper…
Linguistic Pattern Based Optimization of Economic and Spatial Uniformity Criteria in Facility Layout Problems
Jerzy Grobelny, Rafał Michalski
This paper extends prior work on linguistic pattern based facility layout optimization by enhancing the LP Alinks framework with an explicit spatial uniformity criterion. While ear…
Quench, Glow, or Stay Silent: Distance-Controlled Up-Conversion Emission near Metallic Nanowires
Maciej Cwierzona, Michal Zebrowski, Pavel Dziarhai +5
We demonstrate controlled transitions between competing radiative and nonradiative decay channels in the up-conversion luminescence of NaYF4:Er3+/Yb3+ nanocrystals placed in proxim…
Efficient Logic Gate Networks for Video Copy Detection
Katarzyna Fojcik
Video copy detection requires robust similarity estimation under diverse visual distortions while operating at very large scale. Although deep neural networks achieve strong perfor…
