An improved ViBe algorithm based on adaptive detection of moving targets

open access: yesJournal of Measurement Science and Instrumentation, 2020
There exists a Ghost region in the detection result of the traditional visual background extraction(ViBe) algorithm, and the foreground extraction is prone to false detection or missed detection due to environmental changes.

Vision-Based Real-Time Aerial Object Localization and Tracking for UAV Sensing System

open access: yesIEEE Access, 2017
This paper focuses on the problem of vision-based obstacle detection and tracking for unmanned aerial vehicle navigation. A real-time object localization and tracking strategy from monocular image sequences is developed by effectively integrating the ...

Extensive Benchmark and Survey of Modeling Methods for Scene Background Initialization

open access: yesIEEE Transactions on Image Processing, 2017
Scene background initialization is the process by which a method tries to recover the background image of a video without foreground objects in it. Having a clear understanding about which approach is more robust and/or more suited to a given scenario is of great interest to many end users or practitioners.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

IMPROVING THE QUALITY OF REGIONAL TYPOLOGIZATION IN THE RUSSIAN FEDERATION BASED ON INNOVATION DEVELOPMENT INDICATORS USING NEURAL NETWORKS

open access: yesМодели, системы, сети в экономике, технике, природе и обществе
Background. As regional socio-economic data become increasingly complex and the role of innovation grows, accurate regional typologization gains importance as a tool for analysis and for substantiating differentiated regional economic policy.

THz-SAR Vibrating Target Imaging via the Bayesian Method

open access: yesInternational Journal of Antennas and Propagation, 2017
Target vibration bears important information for target recognition, and terahertz, due to significant micro-Doppler effects, has strong advantages for remotely sensing vibrations.

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Systematic Failure of Vision Transformers in Imbalanced Skin Lesion Classification

open access: yesDermato
Background/Objectives: Vision Transformers (ViTs) have demonstrated impressive performance in dealing with large-scale natural image datasets. They have started to be used in medical image classification problems as well.
