BSC-Net: Background Suppression Algorithm for Stray Lights in Star Images

open access: yesRemote Sensing, 2022
Most background suppression algorithms are weakly robust due to the complexity and fluctuation of the star image’s background. In this paper, a background suppression algorithm for stray lights in star images is proposed, which is named BSC-Net ...

Cosmic coincidences: Investigations for neutron background suppression

open access: yesJournal of Research of the National Institute of Standards and Technology, 2007
Two experimental investigations were made in order to reduce background counts in neutron detectors. Each investigation relied upon the fact that neutron background is largely due to cosmic ray interactions with the air and ground. The first attempt was to look at neutron arrival times.

Dim and Small Target Detection Based on Spiral Gradient Optimization Estimation and High-Order Correlation Enhancement

open access: yesIEEE Access, 2022
In order to reduce the influence of strong halo effect on dim small target detection in daytime, a dim small target detection algorithm based on spiral gradient optimization estimation and high-order correlation enhancement is proposed in this paper.

Background Suppression in Frequency-Domain Fluorometry [PDF]

open access: yesAnalytical Biochemistry, 2000
Gated detection is often used in time-domain measurements of long-lived fluorophores for suppression of interfering short-lived autofluorescence. However, no direct method has been available for gated detection and background suppression when using frequency-domain fluorometry.

Infrared Image-Enhancement Algorithm for Weak Targets in Complex Backgrounds

open access: yesSensors, 2023
Infrared small-target enhancement in complex contexts is one of the key technologies for infrared search and tracking systems. The effect of enhancement directly determines the reliability of the monitoring equipment.

Suppression of quantum corrections by classical backgrounds [PDF]

open access: yesPhysical Review D, 2014
We use heat-kernel techniques in order to compute the one-loop effective action in the cubic Galileon theory for a background that realizes the Vainshtein mechanism. We find that the UV divergences are suppressed relative to the predictions of standard perturbation theory at length scales below the Vainshtein radius.

Hierarchical Suppression Based Matched Filter for Hyperspertral Imagery Target Detection

open access: yesSensors, 2020
Target detection in hyperspectral imagery (HSI) aims at extracting target components of interest from hundreds of narrow contiguous spectral bands, where the prior target information plays a vital role.

Self-Erasing Network for Person Re-Identification

open access: yesSensors, 2021
Person re-identification (ReID) plays an important role in intelligent surveillance and receives widespread attention from academics and the industry. Due to extreme changes in viewing angles, some discriminative local regions are suppressed. In addition,

Background suppressing Gabor energy filtering [PDF]

open access: yesPattern Recognition Letters, 2015
In the field of facial emotion recognition, early research advanced with the use of Gabor filters. However, these filters lack generalization and result in undesirably large feature vector size. In recent work, more attention has been given to other local appearance features. Two desired characteristics in a facial appearance feature are generalization
