#X text 60 371 pix_mano is an object that tracks light reflecting objects
(eg. hands) over a light absorbing background (eg. black cloth). Light
reflecting objects need to enter the video frame from one of the sides
to be recognized. For example \, a white circle in the center will
not be recognized as there is no entry point in the borders of the
frame.;
#X text 58 496 Roughly \, the object works by setting a threshold to
discriminate between black and white pixels. shapes formed of white
pixels are analyzed in the order of largest entry section.;
#X text 581 698 support information in www.jaimeoliver.pe;
#X text 59 553 For each object an analysis of its contour is achieved.
(see graph option in outlet two while entering your hand into the frame).
The contours formed by a hand are averaged for smoothing and sampled
\, and then are plotted as x \, y coordinates and variation in angle
with respect to the previous sampled point. An analysis of this contour
provides tips (positive peaks) and valleys (negative peaks);
#X text 76 646 This object was programmed as part of the Silent Percussion
Project \, for use in the MANO Controller. For more information: http://www.jaimeoliver.pe
