Visualization Tracking zone

Set and visualize on the chosen stage a rectangle as a tracking zone.
Output is 1 for inside the zone, 0 outside.
You can hide/show the zone with the key ‘h’ (can be changed)
when the zones are visible, as help for tracking , the zone will highlight ( value of “intensity over”) if an object is inside.
You can choose an other color for every zone.

DO NOT FORGET to set the size of the monitor in Eyes (column, row) or Eyes++ (h res, v res) according to the stage ratio.
