NAME:

track

PURPOSE:

Constructs n-dimensional trajectories from a scrambled list of

particle coordinates determined at discrete times (e.g. in

consecutive video frames).

CATEGORY:

Image Processing

CALLING SEQUENCE:

result = track( positionlist, maxdisp, param )

set all keywords in the space below

INPUTS:

positionlist: an array listing the scrambled coordinates and data

of the different particles at different times, such that:

positionlist(0:d-1,*): contains the d coordinates and

data for all the particles, at the different times. must be positve

positionlist(d,*): contains the time t that the position

was determined, must be integers (e.g. frame number. These values must

be monotonically increasing and uniformly gridded in time.

maxdisp: an estimate of the maximum distance that a particle

would move in a single time interval.- NAME:
