Hi IOhannes

yes i've used the pix_fiducialtrack-help.pd to do the try but nothing happens and objects parameters is not retrieved. I'm on 10.3.9 with pd-0.39.2-extended-test4

thank you very much

Hi guys ù i'm trying to use the object pix_fiducialtrack but it doesn't works while reacTIVision retrive information from the same fiducials. Does anyone have the same problems? Could it be an all.trees file problems? I'm using some of the fiducials found on the "The design and Evolution od fiducials for the reacTIVision System" document.

did you try the pix_fiducialtrack-help.pd ? you really need to do some b/w-thresholding before applying the fiducial tracking; [pix_threshold_bernsen] gives you the algorithm used by reacTIVision.

the all.trees file provided with Gem is stolen from reacTIVision.
