Optimized UAV object tracking framework based on Integrated Particle filter with ego-motion transformation matrix

open access: yesMATEC Web of Conferences, 2017
Vision based object tracking problem still a hot and important area of research specially when the tracking algorithms are performed by the aircraft unmanned vehicle (UAV). Tracking with the UAV requires special considerations due to the flight maneuvers,

Benchmarking of Tracking Codes (BDSIM/DIMAD) using the ILC Extraction Lines [PDF]

open access: yes, 2006
The study of beam transport is of central importance to the design and performance assessment of modern particle accelerators. In this work, we benchmark two contemporary codes - DIMAD and BDSIM, the latter being a relatively new tracking code built ...

Random Time-Scale Invariant Diffusion and Transport Coefficients

open access: yes, 2008
Single particle tracking of mRNA molecules and lipid granules in living cells shows that the time averaged mean squared displacement $\overline{\delta^2}$ of individual particles remains a random variable while indicating that the particle motion is ...

Rapid, topology-based particle tracking for high-resolution measurements of large complex 3D motion fields

open access: yesScientific Reports, 2018
Spatiotemporal tracking of tracer particles or objects of interest can reveal localized behaviors in biological and physical systems. However, existing tracking algorithms are most effective for relatively low numbers of particles that undergo ...

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

open access: yesAdvanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Comparative assessment of pressure field reconstructions from particle image velocimetry measurements and Lagrangian particle tracking

open access: yes, 2017
A test case for pressure field reconstruction from particle image velocimetry (PIV) and Lagrangian particle tracking (LPT) has been developed by constructing a simulated experiment from a zonal detached eddy simulation for an axisymmetric base flow at ...

Multiple object tracking using an automatic veriable-dimension particle filter [PDF]

open access: yes, 2010
Object tracking through particle filtering has been widely addressed in recent years. However, most works assume a constant number of objects or utilize an external detector that monitors the entry or exit of objects in the scene.

A novel particle tracking method with individual particle size measurement and its application to ordering in glassy hard sphere colloids

open access: yes, 2013
Particle tracking is a key to single-particle-level confocal microscopy observation of colloidal suspensions, emulsions, and granular matter. The conventional tracking method has not been able to provide accurate information on the size of individual ...
