Orthogonal Trajectories

Orthogonal Trajectories

Orthogonal trajectories describe the geometric relationship between two families of curves that intersect each other at right angles. One illustrative case involves a family of parabolas that open sideways along the x-axis. These curves share a common shape but differ by a scaling parameter, resulting in a set of curves that all pass through the origin and widen at different rates.Determining Orthogonal TrajectoriesTo identify the orthogonal trajectories for these parabolas, the first step...

Background:

Single particle tracking (SPT) algorithms rely on parameter settings sensitive to time-series characteristics.
Global parameter settings in SPT algorithms perform poorly in spatially inhomogeneous systems.

Purpose of the Study:
