Read a dtrack trajectory file into a TrajSet

Reads a tab-separated, headerless file produced by dtrack (https://bitbucket.org/jochensmolka/dtrack). The file is expected to have at least three columns: frame number, x coordinate, y coordinate. A fourth confidence/flag column (always 1 in practice) is silently dropped.

Usage

dtrack_read(path, normalize_xy = FALSE, ...)

Arguments

path

Path to a dtrack _point02.txt trajectory file.

normalize_xy

Logical; passed to [TrajSet_read()]. Default FALSE because dtrack files are in pixel space.

...

Additional arguments passed to [TrajSet_read()].

Value

A TrajSet.
