#X text 50 12 Synopsis: [pix_fiducialtrack];
#X text 29 57 Description: fiducial (target) detector (and tracker)
;
#X text 17 73 [pix_fiducialtrack] is able to detect \, identify and
track multiple fiducials (targets with a unique topology as expressed
by the region adjacency graph) within an image.;
#X text 19 115 the tracking system is the one used in the reacTable*
(http://iua.upf.edu.es/mtg/reacTable) \, and is (c) by Ross Bencina
and Martin Kaltenbrunner. for more information on how it works \, see
the homepage of reacTable*.;
#X text 15 175 [pix_fiducialtrack] needs a dictionary-file for the
used fiducials \, which can be given either via an argument or with
the "open"-message. The default file is "all.trees";
#X text 64 289 symbol: dictionary-file for TreeIdMap;

#X text 20 428 for good result you will need some intelligent thresholding:
;
#X obj 451 87 pix_grey;
#X text 16 221 [pix_fiducialtrack] only works on b/w grayscale-images
\, so you need some pre-processing (colorconversion \, thresholding)
