Detailed Description

ThresholdedTransformation represents a thresholded image transformation in PCL. A thresholded transformation modifies its effect when applied to pixels within a given range of pixel sample values.

Instead of defining a fixed range of sample values, a thresholded transformation defines two threshold values in PCL. These thresholds are normalized distances measured from a floating reference value that can be specified on a per-pixel basis.

In PCL, convolutions in the spatial domain and morphological transformations have been implemented as thresholded transformations.

Constructor & Destructor Documentation

◆ ThresholdedTransformation() [1/2]

pcl::ThresholdedTransformation::ThresholdedTransformation	(	double	low = `0`,
		double	high = `0`
	)

inline

Constructs a ThresholdedTransformation object with the specified low and high threshold values in the normalized real range [0,1].

Definition at line 90 of file ThresholdedTransformation.h.

◆ ThresholdedTransformation() [2/2]

pcl::ThresholdedTransformation::ThresholdedTransformation ( const ThresholdedTransformation & )

default

Copy constructor.

◆ ~ThresholdedTransformation()

pcl::ThresholdedTransformation::~ThresholdedTransformation ( )

inlineoverride

Destroys a ThresholdedTransformation object.

Definition at line 104 of file ThresholdedTransformation.h.

Member Function Documentation

◆ HighThreshold()

double pcl::ThresholdedTransformation::HighThreshold ( ) const

inline

Returns the current high threshold in the normalized real range.

Definition at line 140 of file ThresholdedTransformation.h.

◆ IsThresholded()

bool pcl::ThresholdedTransformation::IsThresholded ( ) const

inline

Returns true iff this transformation is currently thresholded.

The transformation is thresholded when either threshold (low or high) is nonzero. When both thresholds are zero, the transformation applies no thresholding at all.
