Detailed Description

A diagonal structure of size 5 is defined as follows:

x · · · x
· x · x ·
· · x · ·
· x · x ·
x · · · x

where existing elements are marked as 'x' and nonexisting elements are denoted as '·'.

Constructor & Destructor Documentation

◆ DiagonalStructure() [1/2]

pcl::DiagonalStructure::DiagonalStructure ( int  size)
inline

Constructs a diagonal structure of the specified size.

Definition at line 634 of file StructuringElement.h.

◆ DiagonalStructure() [2/2]

pcl::DiagonalStructure::DiagonalStructure ( const DiagonalStructure &  )
default

Copy constructor.

Member Function Documentation

◆ Clone()

StructuringElement* pcl::DiagonalStructure::Clone ( ) const
inlineoverridevirtual

Returns a pointer to a dynamically allocated duplicate of this structuring element.

Implements pcl::StructuringElement.

Definition at line 646 of file StructuringElement.h.

◆ ElementExists()

bool pcl::DiagonalStructure::ElementExists ( int  i,
int  j,
int  k 
) const
inlineoverridevirtual

Returns true iff a given element exists in this structure.

Parameters
icolumn position (X-coordinate) of the requested structure element. Must be 0 <= i < n, where n is the structure size.
jrow position (Y-coordinate) of the requested structure element. Must be 0 <= j < n, where n is the structure size.
kWay index. Must be 0 <= k < m, where m is the number of ways defined in this structure.

Reimplemented from pcl::StructuringElement.

Definition at line 666 of file StructuringElement.h.

◆ IsBox()

bool pcl::DiagonalStructure::IsBox ( int  k) const
inlineoverridevirtual

Returns true iff this is a box structure. All elements in a box structure are existing elements.

As reimplemented by DiagonalStructure, this member function always returns false.

Reimplemented from pcl::StructuringElement.

Definition at line 658 of file StructuringElement.h.
