tabletop_object_detector with kinect [closed]

edit

I am trying to use tabletop_object_detector for recognizing image that is in household_object_database. But there is neither any segmented table, not any segmented/recognized object. I am modifying the parameter file of tabletop_complete.launch====> <arg name="tabletop_segmentation_points_input" default="camera/depth/points"/>

which ever parameter I am using the node is running.This is my output:==>

core service [/rosout] found process[tabletop_segmentation-1]: started with pid [18322] process[tabletop_object_recognition-2]: started with pid [18323] process[tabletop_complete_node-3]: started with pid [18374] Please help me anybody
