Theoretical Comparison of Real-Time Single Particle Tracking Techniques

Real-time nanomicroscopy via three-dimensional single-particle tracking.

We developed a new method for real-time, three-dimensional tracking of fluorescent particles. The instrument is based on a laser-scanning confocal microscope where the focus of the laser beam is scanned or orbited around the particle. Two confocal pinholes are used to simultaneously monitor regions immediately above and below the particle and a feedback loop is used to keep the orbit centered o...

Real-Time Interference Detection in Tracking Loop of GPS Receiver

Global Positioning System (GPS) spoofing could pose a major threat for GPS navigation ‎systems, so the GPS users have to gain a better understanding of the broader implications of ‎GPS.‎ In this paper, a plenary anti-spoofing approach based on correlation is proposed to distinguish spoofing effects. The suggested ‎method can be easily implemented in tracking loop of GPS receiver...

Real-time visual tracking using correlation techniques

A real-time correspondence based tracking algorithm is detailed. The system uses a pipeline processor , a general purpose processor, a camera and a display. The Minimum Noise and Correlation Energy (MINACE) lter is used in the tracking algorithm as it provides a good combination of speed, accuracy and exibility for the targeted hardware system. The system designed is fast and tracking is accomp...

Real-time multi-parameter spectroscopy and localization in three-dimensional single-particle tracking.

Tracking of single particles in optical microscopy has been employed in studies ranging from material sciences to biophysics down to the level of single molecules. The technique intrinsically circumvents ensemble averaging and may therefore reveal directly mechanistic details of the involved dynamic processes. Such processes range from translational and rotational motion to spectral dynamics. W...
