A Vision-Based Particle Tracking Velocimetry

Real-Time Imaging, 2001
Summary: Particle Image Velocimetry (PIV) is a non-intrusive optical technique to measure velocity of flows. It provides the simultaneous visualization of the streamline pattern in unsteady flows and the quantification of the velocity field over the image plane. To reveal the flow motion, the flow is seeded by small scattering particles.

Collaborative particle filters for group tracking

2010 IEEE International Conference on Image Processing, 2010
Tracking groups of people is a highly informative task in surveillance, and it represents a still open and little explored issue. In this paper, we propose a brand new framework for group tracking, that consists in two separate particle filters, one focusing on groups as atomic entities (the multi-group tracker), and the other modeling each individual ...

Methods for Cell and Particle Tracking

2012
Achieving complete understanding of any living thing inevitably requires thorough analysis of both its anatomic and dynamic properties. Live-cell imaging experiments carried out to this end often produce massive amounts of time-lapse image data containing far more information than can be digested by a human observer.

The Probe Rules in Single Particle Tracking

Current Protein & Peptide Science, 2011
Single particle tracking (SPT) enables light microscopy at a sub-diffraction limited spatial resolution by a combination of imaging at low molecular labeling densities and computational image processing. SPT and related single molecule imaging techniques have found a rapidly expanded use within the life sciences.

Volume‐tracking of subgrid particles

International Journal for Numerical Methods in Fluids, 2011
AbstractA new PLIC‐VOF method is proposed to track deformable particles, such as bubbles and liquid droplets, that can be smaller than the grid spacing. The idea is to replace the surface normal (SN) calculation used in the PLIC, by the SN vector obtained from partial differential equations that are solved together with the advection algorithm.

Tracks of -Particles in Helium

Nature, 1923
IN a recent issue of NATURE (January 27, p. 114). Messrs. Ryan and Harkins have published some photographs of the ionisation tracks of recoiling atoms produced by collision of -particles with air molecules. We have been also engaged in photographing the tracks of -particles from polonium in helium, and have obtained some interesting photographs ...

Multiple particle tracking

2017
AbstractThe fundamentals and best practices of multiple particle tracking microrheology are discussed, including methods for producing video microscopy data, analyzing data to obtain mean-squared displacements and displacement correlations, and, critically, the accuracy and errors (static and dynamic) associated with particle tracking.
