Particle Tracks and Fission Tracks
1992A fast charged particle, when passing through an insulating solid, creates a narrow trail of damage along its trajectory. This damage trail persists in the solid after the particle has come to rest and is called a charged particle track or nuclear track. The solid in which the tracks are registered is commonly called the detector.

Touch tracking with a particle filter
Machine Vision and Applications, 2013We report on a system for multi-touch tracking from linescan cameras using particle filters. We show that a particle filter incorporating a local search element is almost as accurate as an exhaustive search algorithm and is significantly faster as the number of touches increases. The system achieves over 95 % correct tracking with an error tolerance of

A Vision-Based Particle Tracking Velocimetry
Real-Time Imaging, 2001Summary: 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, 2010Tracking 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
2012Achieving 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, 2011Single 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, 2011AbstractA 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, 1923IN 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 ...
