Hi list, Hi Hans, I really liked using pdp_mgrid why I allowed to follow each of the points that I requested, even could make conditional for each of the points of intersection, not only on an axis. The object pix_blob also gave me those readings, but always so noisy and erratic, usually can detect the presence and the occasional movement, have a leading colleagues have recommended pix_background, but no taste, what recommend you to detect exactly each quadrant? ... ideal would be a kind of grid. Gridflow have also recommended, but still can not quite decipher the code.
Thanks for responding. Best regards José 2010/12/8 Hans-Christoph Steiner <h...@at.or.at> > > Which kind of tracking to do want to do? It should be pretty easy to a > motiongrid as an abstraction.
