Detailed Description

The selection morphological operator (or selection order-statistic filter) computes the value corresponding to a prescribed percentile in the ranked set of values from a pixel neighborhood.

The selection point k of the selection operator defines the working percentile: for k=0, we have an erosion (or minimum) operator; for k=1 we have a dilation (or maximum) operator; k=0.5 defines the median operator. Other values work as a balance between erosion and dilation.

Constructor & Destructor Documentation

◆ SelectionFilter() [1/3]

pcl::SelectionFilter::SelectionFilter ( )
default

Default constructor. The default selection point is 0.5, equivalent to a median operator.

◆ SelectionFilter() [2/3]

pcl::SelectionFilter::SelectionFilter ( float  p)
inline

Constructs a SelectionFilter with selection point p.

Definition at line 910 of file MorphologicalOperator.h.

◆ SelectionFilter() [3/3]

pcl::SelectionFilter::SelectionFilter ( const SelectionFilter &  )
default

Copy constructor.
