Hi Shahmi, I think the twoLevelMTTD_stack could be interesting for you. ( www.ros.org/wiki/twoLevelMTTD_stack ) Actually I'm writing some wiki pages on it (work in progress, so some information are not completed yet). If that stack is useful for you, a feedback will be appreciate. Hope this help, Enea Scioni -- View this message in context: http://ros-users.122217.n3.nabble.com/Any-Packages-Using-Multi-layer-People-Detection-using-2D-Laser-Scanner-tp1877172p1877975.html Sent from the ROS-Users mailing list archive at Nabble.com.
