Adaptive multi-layer structure with spatial-spectrum combination for hyperspectral image anomaly detection

open access: yesXibei Gongye Daxue Xuebao, 2021
A new algorithm for hyperspectral image anomaly detection is proposed by designing an adaptive multi-layer structure with spatial-spectral combination information, which is different from the traditional anomaly detection algorithms only considering the ...

Background suppression in the JUNO experiment [PDF]

open access: yesProceedings of 38th International Conference on High Energy Physics — PoS(ICHEP2016), 2017
The JUNO (Jiangmen Underground Neutrino Observatory) experiment is under preparation in China by the international collaboration. The main goal of the project is to determine the neutrino mass hierarchy by precise measurement of the energy spectrum of the antineutrinos from the nuclear reactors with the help of the 20 kt liquid scintillator underground

Point spread character based low SNR single pixel infrared target detection

open access: yesThe Journal of Engineering, 2019
Robust and efficient low signal-to-noise ratio (SNR) single pixel infrared (IR) target detection has been a key technique in IR searching and tracking system. However, there exist two critical difficulties, i.e. noise disturbance and low contrast between

Echo pulses for background suppression by optimal control

open access: yesMagnetic Resonance in Chemistry, 2023
AbstractMaterials used to construct magic‐angle‐spinning NMR probes can contain NMR active nuclei that produce a significant amount of background signal. Because these materials are located outside the sample coil, the use of spatially selective pulses to remove the background is a popular approach for background suppression.

Sparse Weighted Constrained Energy Minimization for Accurate Remote Sensing Image Target Detection

open access: yesRemote Sensing, 2017
Target detection is an important task for remote sensing images, while it is still difficult to obtain satisfied performance when some images possess complex and confusion spectrum information, for example, the high similarity between target and ...

Multi-Level Convolutional Network for Ground-Based Star Image Enhancement

open access: yesRemote Sensing, 2023
The monitoring of space debris is important for spacecraft such as satellites operating in orbit, but the background in star images taken by ground-based telescopes is relatively complex, including stray light caused by diffuse reflections from celestial

Crowd Counting Network Based on Background Suppression and Context Awareness [PDF]

open access: yesJisuanji gongcheng, 2022
To reduce the influence of background noise and perspective distortion in crowd counting tasks, a new network based on background suppression and context awareness is proposed.VGG-16 network is used to extract image features, which are input into Density

Eye contact facilitates awareness of faces during interocular suppression [PDF]

open access: yes, 2011
Eye contact captures attention and receives prioritized visual processing. Here we asked whether eye contact might be processed outside conscious awareness. Faces with direct and averted gaze were rendered invisible using interocular suppression.
