Functions

geometry_msgs::Point32 cloud_geometry::statistics::computeMedian (const sensor_msgs::PointCloud &points)
 Compute the median value of a 3D point cloud and return it as a Point32.
geometry_msgs::Point32 cloud_geometry::statistics::computeMedian (const sensor_msgs::PointCloud &points, const std::vector< int > &indices)
 Compute the median value of a 3D point cloud using a given set point indices and return it as a Point32.
double cloud_geometry::statistics::computeMedianAbsoluteDeviation (const sensor_msgs::PointCloud &points, double sigma)
 Compute the median absolute deviation:

\[ MAD = \sigma * median_i (| Xi - median_j(Xj) |) \]

.

double cloud_geometry::statistics::computeMedianAbsoluteDeviation (const sensor_msgs::PointCloud &points, const std::vector< int > &indices, double sigma)
 Compute the median absolute deviation:

\[ MAD = \sigma * median_i (| Xi - median_j(Xj) |) \]

.

void cloud_geometry::statistics::getChannelMeanStd (const sensor_msgs::PointCloud &points, int d_idx, double &mean, double &stddev)
 Compute both the mean and the standard deviation of a channel/dimension of the cloud.
void cloud_geometry::statistics::getChannelMeanStd (const sensor_msgs::PointCloud &points, const std::vector< int > &indices, int d_idx, double &mean, double &stddev)
 Compute both the mean and the standard deviation of a channel/dimension of the cloud using indices.
void cloud_geometry::statistics::getTrimean (std::vector< int > values, double &trimean)
 Compute both the trimean (a statistical resistent L-Estimate) of an array of values.
void cloud_geometry::statistics::selectPointsInsideDistribution (const sensor_msgs::PointCloud &points, const std::vector< int > &indices, int d_idx, double mean, double stddev, double alpha, std::vector< int > &inliers)
 Determines a set of point indices inside of a +/- * distribution interval, in a given channel space, where and are the mean and the standard deviation of the channel distribution.
void cloud_geometry::statistics::selectPointsOutsideDistribution (const sensor_msgs::PointCloud &points, const std::vector< int > &indices, int d_idx, double mean, double stddev, double alpha, std::vector< int > &inliers)
 Determines a set of point indices outside of a +/- * distribution interval, in a given channel space, where and are the mean and the standard deviation of the channel distribution.
