Detailed Description

template<>
class pcl::ExtractIndices< sensor_msgs::PointCloud2 >

ExtractIndices extracts a set of indices from a point cloud.
Usage examples:

 pcl::ExtractIndices<PointType> filter;
 filter.setInputCloud (cloud_in);
 filter.setIndices (indices_in);
 // Extract the points in cloud_in referenced by indices_in as a separate point cloud:
 filter.filter (*cloud_out);
 // Retrieve indices to all points in cloud_in except those referenced by indices_in:
 filter.setNegative (true);
 filter.filter (*indices_out);
 // The resulting cloud_out is identical to cloud_in, but all points referenced by indices_in are made NaN:
 filter.setNegative (true);
 filter.setKeepOrganized (true);
 filter.filter (*cloud_out);

Note:

Does not inherently remove NaNs from results, hence the extract_removed_indices_ system is not used.
