[PD] Tracking color with GEM+Pdp

[Olivier Baudu]

Thank you Yves,
Even if your [pdp_ctrack] seems to be more powerfull in my situation than
[pdp_opencv_colorfilt], I've discovered Open CV library... great...

Thank you too, William,
[pix_colortrack] looks intersting but I'm in the same situation as Pedro...
Whithout more informations in the "src" folder of this external's source, I
realy don't know how to compile it...
(But I confess that my knowledge in compilation is very poor...).

01vier.
