tracking: Object tracking

In tkatsuki/dipr: Digital Image Processing with R

Description

These functions are for tracking and analyzing objects in movies. tracking calculates various values related to object motion. trackDistance calculates distance traveled by objects during the specified time window. trackSpeed calculates average speed of objects during the specified time window. angularVelocity calculates angular velocity of moving objects. msd calculates mean square diviation of object trajectories.

Usage

angularVelocity(xy, bin = 5, interval = 1)

msd(xy)

trackDistance(xy, unit = 1)

trackSpeed(dist, bin = 5, interval = 1)

tracking(rdir, mask = NULL, w = 0, h = 0, maxdist = 20, bin = 3,
  interval = 0.1, unit = 1, size = NULL, ftrs = NULL)

Arguments

xy	A matrix of object coordinates.
bin	Window size for averaging.
interval	Time intervals.
unit	Unit length.
dist	Traveled distance (e.g. the output of trackDistance).
mask	Labeled binary movie.
maxdist	Maximum distance for object association.
size	Maximum size difference for objects association.
xy	A target image of Image object or an array.

Examples

angularVelocity()
msd()
trackDistance()
trackSpeed()
