Detailed Description

InterlacedTransformation represents an interlaced image transformation in PCL. An interlaced transformation can be applied to a subset of the pixels in a target image by acting exclusively on selected rows and columns of pixels, distributed at regular intervals.

The distance between two consecutive rows or columns of transformed pixels is the interlacing distance that characterizes an interlaced transformation. Intermediate pixels falling between selected rows or columns are ignored during the transformation.

In PCL, convolutions in the spatial domain and morphological transformations have been implemented as interlaced transformations. A good example of interlaced image transformation algorithm is the starlet transform (see the StarletTransform class), which uses interlaced convolutions to perform a multiscale decomposition.

Constructor & Destructor Documentation

InterlacedTransformation() [1/2]

pcl::InterlacedTransformation::InterlacedTransformation ( int  n = 1 )

inline

Constructs an InterlacedTransformation object with the specified interlacing distance n > 0 in pixels.

Definition at line 96 of file InterlacedTransformation.h.

InterlacedTransformation() [2/2]

pcl::InterlacedTransformation::InterlacedTransformation ( const InterlacedTransformation &  )

default

Copy constructor.

~InterlacedTransformation()

pcl::InterlacedTransformation::~InterlacedTransformation ( )

inlineoverride

Destroys an InterlacedTransformation object.

Member Function Documentation

DisableInterlacing()

void pcl::InterlacedTransformation::DisableInterlacing ( )

inline

Disables interlacing for this transformation.

This is a convenience function, equivalent to:

SetInterlacingDistance( 1 ); 

Definition at line 161 of file InterlacedTransformation.h.

InterlacingDistance()

int pcl::InterlacedTransformation::InterlacingDistance ( ) const

inline

Returns the current interlacing distance of this transformation in pixels.

See also

SetInterlacingDistance(), IsInterlaced()

Definition at line 133 of file InterlacedTransformation.h.

IsInterlaced()

bool pcl::InterlacedTransformation::IsInterlaced ( ) const

inline

Returns true iff this transformation is currently interlaced.

The transformation is interlaced if the current interlacing distance is greater than one pixel.

See also

InterlacingDistance()

Definition at line 122 of file InterlacedTransformation.h.

SetInterlacingDistance()

void pcl::InterlacedTransformation::SetInterlacingDistance ( int  n )

inline

Sets the current interlacing distance of this transformation to the specified value n > 0 in pixels.

The interlacing distance is the distance in pixels between two consecutive rows or columns of transformed pixels. Intermediate pixels falling between selected rows or columns are ignored.
