Detailed Description

template<typename T>
class pcl::BicubicFilterInterpolation< T >

Bicubic filter interpolation uses a cubic filter (an instance of CubicFilter or a derived class) to interpolate pixel values in a rectangular pixel matrix of the specified horizontal and vertical radii. Thanks to the separability of cubic filters, BicubicFilterInterpolation can be applied with a different filter size on each axis.

Constructor & Destructor Documentation

BicubicFilterInterpolation() [1/2]

template<typename T >

pcl::BicubicFilterInterpolation< T >::BicubicFilterInterpolation ( int  rx, int  ry, const CubicFilter &  filter  )

inline

Constructs a new BicubicFilterInterpolation instance.

Parameters

rx,ry	Horizontal and vertical interpolation radii, respectively, in pixels. Both radii must be >= 1. Interpolation will take place in a rectangular pixel matrix with 2*rx + 1 columns and 2*ry + 1 rows.
filter	Reference to a CubicFilter instance that will be used as the interpolation filter.

Member Function Documentation

Filter()

template<typename T >

const CubicFilter& pcl::BicubicFilterInterpolation< T >::Filter ( ) const

inlinenoexcept

Returns a constant reference to the cubic filter being used by this interpolation.

Definition at line 626 of file BicubicFilterInterpolation.h.

HorizontalRadius()

template<typename T >

int pcl::BicubicFilterInterpolation< T >::HorizontalRadius ( ) const

inlinenoexcept

Returns the horizontal interpolation radius in pixels.

Definition at line 582 of file BicubicFilterInterpolation.h.

Initialize()

template<typename T >

void pcl::BicubicFilterInterpolation< T >::Initialize ( const T *  data, int  width, int  height  )

inlineoverridevirtual

Initializes a new interpolation.

Parameters

data	Two-dimensional matrix of function values stored in row-order. Must remain valid and accessible while this object is used to compute interpolated function values.
width	Horizontal dimension (most rapidly varying coordinate) of the data array.
height	Vertical dimension (most slowly varying coordinate) of the data array.

Reimplemented from pcl::BidimensionalInterpolation< T >.

operator()()

template<typename T >

PCL_HOT_FUNCTION double pcl::BicubicFilterInterpolation< T >::operator() ( double  x, double  y  ) const

inlineoverridevirtual

Returns an interpolated value at {x,y} location.

Parameters

x,y	Coordinates of the interpolation point (horizontal,vertical).

Interpolation takes place on a rectangular matrix whose center is the nearest pixel to {x, y}. The interpolation matrix has 2*rx + 1 columns and 2*ry + 1 rows, where rx and ry are the horizontal and vertical interpolation radii, respectively.

Implements pcl::BidimensionalInterpolation< T >.

SetFilter()

template<typename T >

void pcl::BicubicFilterInterpolation< T >::SetFilter ( const CubicFilter &  filter )

inline

Sets a new cubic filter to be applied by this interpolation.

Definition at line 634 of file BicubicFilterInterpolation.h.

SetRadii()

template<typename T >

void pcl::BicubicFilterInterpolation< T >::SetRadii ( int  rx, int  ry  )

inline

Sets new interpolation radii.

Parameters

rx,ry

Horizontal and vertical interpolation radii, respectively, in pixels. Both radii must be >= 1. Interpolation will take place in a rectangular pixel matrix with 2*rh + 1 columns and 2*rv + 1 rows.

Definition at line 603 of file BicubicFilterInterpolation.h.

VerticalRadius()

template<typename T >

int pcl::BicubicFilterInterpolation< T >::VerticalRadius ( ) const

inlinenoexcept

Returns the vertical interpolation radius in pixels.
