Tracking algorithms

One of these models the plume itself, attempting to provide a predictive capability for describing the characteristics of the plume in a measured environment. Knowing the motion characteristics of the medium—air or water—the models seek to predict the concentration and dimensions of the plume at distances downstream. Of course, the nature of the problem quickly leads to use of statistical descriptions. This provides a model quite adequate for constructing tracking algorithms. 

The method proceeds in three stages. The first stage involves estimation of the tonal components using a DFT magnitude-based peak tracking algorithm closely related to...

The particle-tracking algorithm is tested for the rigid body rotation of fluid in a circular channel as shown in Fig. 8. The radius of the outer boundary and the width of the channel are set to = 1 and = 0.2, respectively. The velocity field is specified as u =yo y and v = x -Xo where x andy are the two-dimensional Cartesian coordinates and and... 

Fig. 8b, the drop makes rigid body motion as expected indicating the accuracy of the tracking algorithm. Accuracy of the tracking algorithm is quantified in Fig. 9. As can be seen in Fig. 9a, b, the tracking algorithm is second order accurate both in time and space.

A sample particle is immobilized on a slide and the measurement noise (X easCO) is calculated with the help of a particle-tracking algorithm. 

In a separate experiment, a sample particle is allowed to freely diffuse in the fluid, while its center of mass is estimated at regular time intervals (30 ms suffices for a micron-sized particle in water at room temperature) using the particle-tracking algorithm. 

Particle tracking algorithms have also been used successfully in measurements of two- and three-dimensional diffusion [9], slip velocity [10], and colloidal electrokinetics [11]. In the context of experimental fluid mechanics studies, researchers found that the Brownian, thermal motion of sub-micron-sized particles suspended in a fluid is significant and may mask the...
