One is the disc, one is with psuedocolor change black to green, and one takes that and filters out green. As you can see there is still some other things picked up by RoboRealm.<p><a target=_blank href="http://www.roborealm.com/uploads/26022_1.png"><img border=1 src="http://www.roborealm.com/uploads/26022_thumb_1.jpg"></a>&nbsp;<a target=_blank href="http://www.roborealm.com/uploads/26022_2.png"><img border=1 src="http://www.roborealm.com/uploads/26022_thumb_2.jpg"></a>&nbsp;<a target=_blank href="http://www.roborealm.com/uploads/26022_3.png"><img border=1 src="http://www.roborealm.com/uploads/26022_thumb_3.jpg"></a>&nbsp;<br> http://www.roborealm.com/forum/index.php?thread_id=4962 http://www.roborealm.com/forum/index.php?thread_id=4962 Tue, 30 Nov 1999 00:11:00 EST Do you have an example image?<br><br>STeven. http://www.roborealm.com/forum/index.php?thread_id=4962 http://www.roborealm.com/forum/index.php?thread_id=4962 Tue, 30 Nov 1999 00:11:00 EST I am trying to track a black, velcro covered disc, similar to a hockey puck. I was going to use pseudo-color to change black to green and then filtering out green. It seems to work but it doesn't filter out all the other colors.
