Detailed Description
template<typename PointT>
class pcl::LocalMaximum< PointT >
LocalMaximum downsamples the cloud, by eliminating points that are locally maximal.
The LocalMaximum class analyzes each point and removes those that are found to be locally maximal with respect to their neighbors (found via radius search). The comparison is made in the z dimension only at this time.
