	<!-- marker tracking
 
	Tracked markers are defined by their ID in the config file (here markerboard_1-20.cfg). 
	The option 'n_marker' allows you limit detection to the first n markers in the file.
	Here, only the first marker (ID=001) will be tracked (see marker001.JPG).
 
	'markerALL.gif' includes all 512 markers (taken from http://handheldar.icg.tugraz.at/artoolkitplus.php)
