Equivalent Modeling and Calculation of the Infrared Characteristics of Combined Multi-Regular Triangular Pyramid Cavity Structures Based on Cavity Radiation Theory [PDF]

open access: yesSensors
To address the high computational complexity of evaluating the infrared radiation characteristics of combined multi-regular triangular pyramid cavity structures and the low efficiency of direct numerical simulation, this paper proposes an equivalent ...

Extracting the abstraction pyramid from complex networks [PDF]

open access: yesBMC Bioinformatics, 2010
Background At present, the organization of system modules is typically limited to either a multilevel hierarchy that describes the "vertical" relationships between modules at different levels (e.g., module A at level two is included in module B at level ...

MS-PANet: Multi-Scale Spatial Pyramid Attention for Effective Drainage Pipeline Image Dehazing [PDF]

open access: yesJournal of Imaging
Urban drainage pipelines are crucial for flood control, drainage, and environmental quality. However, fog within pipelines degrades image quality, hindering the identification of damage features such as cracks and leaks.

Azimuth-Sensitive Object Detection of High-Resolution SAR Images in Complex Scenes by Using a Spatial Orientation Attention Enhancement Network

open access: yesRemote Sensing, 2022
The scattering features of objects in synthetic aperture radar (SAR) imagery are highly sensitive to different azimuth angles, and detecting azimuth-sensitive objects in complex scenes becomes a challenging task. To address this issue, we propose a novel

Object Detection Based on Global-Local Saliency Constraint in Aerial Images

open access: yesRemote Sensing, 2020
Different from object detection in natural image, optical remote sensing object detection is a challenging task, due to the diverse meteorological conditions, complex background, varied orientations, scale variations, etc.

Efficient adaptive feature aggregation network for low-light image enhancement.

open access: yesPLoS ONE, 2022
Existing learning-based methods for low-light image enhancement contain a large number of redundant features, the enhanced images lack detail and have strong noises. Some methods try to combine the pyramid structure to learn features from coarse to fine,

Exploration of the pyramid complex of King Djedkare: 2019 fall season [PDF]

open access: yesPražské Egyptologické Studie, 2020
The recent fieldwork of the Egyptian mission in the pyramid temple of King Djedkare focused on cleaning and documenting three major areas. The temple area immediately south of the columned courtyard provided no firm evidence for reconstructing the layout

Unsupervised Horizontal Pyramid Similarity Learning for Cross-Domain Adaptive Person Re-Identification

open access: yesIEEE Access, 2021
Although person re-identification has made great progress, unsupervised cross-domain adaptive person re-identification is still a challenging problem. With no labeled data in target domain, the performance may have a significant drop.
