MLS Nodelet in pcl_ros

edit

Can someone give me an exmaple of how to use the MLS nodelet from the pcl_ros package? My code is as follows:

<node name="mls" pkg="nodelet" type="nodelet" args="load pcl/MovingLeastSquares /camera/camera_nodelet_manager" respawn="true">
    <remap from="~input" to="/camera/depth/points"/>
    <remap from="~output" to="/camera/depth/smooth_points"/>
    <param name="radius_search" value="0.05"/>
    <param name="spatial_locator" value="1"/> #FLANN
</node>

I can view and modify the parameters in tyhe rqt gui, but it says no inliers found for the following plane segmentor nodelet that I have. The other nodelets I have work fine except when I try to use MLS to smooth it out first. Thank you!

I am using ROS Indigo and Ubuntu 14.04.
