Research on Background Learning Correlation Filtering Algorithm With Multi-Feature Fusion

open access: yesIEEE Access, 2023
Aiming at the problems of occlusion, drift, and background change in visual image tracking, a background learning correlation filtering algorithm based on multi-feature fusion is proposed.

Water balance for gaged watersheds in the Central Sierra Nevada, California and Nevada, United States

open access: yesFrontiers in Forests and Global Change, 2022
Watershed managers require accurate, high-spatial-resolution evapotranspiration (ET) data to evaluate forest susceptibility to drought or catastrophic wildfire, and to determine opportunities for enhancing streamflow or forest resilience under climate ...

Population Size Estimation of Men Who Have Sex with Men in Tbilisi, Georgia; Multiple Methods and Triangulation of Findings. [PDF]

open access: yesPLoS ONE, 2016
INTRODUCTION:An accurate estimation of the population size of men who have sex with men (MSM) is critical to the success of HIV program planning and to monitoring of the response to epidemic as a whole, but is quite often missing.

Bootstrap confidence sets under model misspecification [PDF]

open access: yes, 2014
A multiplier bootstrap procedure for construction of likelihood-based confidence sets is considered for finite samples and a possible model misspecification. Theoretical results justify the bootstrap validity for a small or moderate sample size and allow

Fast Tracking Algorithm Based on Spatial Regularization Correlation Filter

open access: yesInformation, 2022
To solve the problem of the redundant number of training samples in a correlation filter-based tracking algorithm, the training samples were implicitly extended by circular shifts of the given target patches, and all the extended samples were used as ...

On reliability-based structural optimisation using stochastic quasigradient methods/Zur zuverlässigkeitstheoretisch gestützten tragwerks-optimierung mit verfahren der stochastischen Quasigra-dienten

open access: yesJournal of Civil Engineering and Management, 1995
Methodical aspects of the reliability-based structural optimisation using stochastic quasigradient methods are considered. For an example of the simply supported reinforced concrete beam, the employment of the Lagrange multiplier method that belongs to ...

A Novel Anti-Drift Visual Object Tracking Algorithm Based on Sparse Response and Adaptive Spatial-Temporal Context-Aware

open access: yesRemote Sensing, 2021
Correlation filter (CF) based trackers have gained significant attention in the field of visual single-object tracking, owing to their favorable performance and high efficiency; however, existing trackers still suffer from model drift caused by boundary ...

Simultaneous likelihood-based bootstrap confidence sets for a large number of models [PDF]

open access: yes, 2015
The paper studies a problem of constructing simultaneous likelihood-based confidence sets. We consider a simultaneous multiplier bootstrap procedure for estimating the quantiles of the joint distribution of the likelihood ratio statistics, and for ...

Forest ownership changes and regional development in Finland

open access: yesSilva Fennica, 1975
The study sought to establish, whether a connection between forest ownership changes and regional differentiation process exists. Data were collected by interviewing fifty persons representing regional planning and forestry. In 1969–72 forest land area

An Adaptive and Scalable Protection Coordination System of Overcurrent Relays in Distributed-Generator-Integrated Distribution Networks

open access: yesApplied Sciences, 2021
Integration of distributed generators (DGs) into a distribution network (DN) can cause coordination challenges of overcurrent relays (OCRs) because of different fault-current contributions of DGs as well as the directional change in fault currents ...
