pcl\_openni\_feature\_persistence

## NAME

pcl\_openni\_feature\_persistence - pcl\_openni\_feature\_persistence

## DESCRIPTION

OpenNIFeaturePersistence - show persistent features based on the MultiscaleFeaturePersistence class using the FPFH features

usage: pcl\_openni\_feature\_persistence \<device\_id\> \<options\>

**where options are:**

**-octree\_leaf\_size** X = size of the leaf for the octree-based subsampling filter (default: 0.02

**-normal\_search\_radius** X = size of the neighborhood to consider for calculating the local plane and extracting the normals (default: 0.041

**-persistence\_alpha** X = value of alpha for the multiscale feature persistence (default: 1.2

**-scales** X1 X2 ... = values for the multiple scales for extracting features (default: 0.21 0.32
