Detailed Description

template<typename TInputPixelType, typename TOutputPixelType>
class itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >

Performs the Hough Transform to find 2D straight lines in a 2D image.

This filter derives from ImageToImageFilter. The input is an image, and all pixels above some threshold are those to be extracted. The output is the image of the accumulator. GetLines() returns a list of LinesSpatialObjects.

Lines are parameterized in the form:

\( R = x \cos(\theta) + y \sin(\theta) \) where \(R\) is the perpendicular distance from the origin and \(\theta\) the angle with the normal.

The output is the accumulator array:

The size of the array depends on the AngleAxisSize that could be set (500 by default) for the angle axis. The distance axis depends on the size of the diagonal of the input image.

static

Method for creation through the object factory.

◆ PrintSelf()

template<typename TInputPixelType , typename TOutputPixelType >
void itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
overrideprotectedvirtual

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::ProcessObject.

◆ SetAngleResolution()

template<typename TInputPixelType , typename TOutputPixelType >
virtual void itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::SetAngleResolution ( double  _arg)
virtual

Set/Get the resolution angle. The Hough space describes (in the angle direction) [-PI,PI[ with a constant step AngleResolution.

◆ SetDiscRadius()

template<typename TInputPixelType , typename TOutputPixelType >
virtual void itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::SetDiscRadius ( double  _arg)
virtual

Set/Get the radius of the disc to remove from the accumulator for each line found.

◆ SetNumberOfLines()

template<typename TInputPixelType , typename TOutputPixelType >
virtual void itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::SetNumberOfLines ( LinesListSizeType  _arg)
virtual

Set/Get the number of lines to extract

◆ SetThreshold()

template<typename TInputPixelType , typename TOutputPixelType >
virtual void itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::SetThreshold ( double  _arg)
virtual

Set/Get the threshold above which the filter should consider the point as a valid point.

◆ SetVariance()

template<typename TInputPixelType , typename TOutputPixelType >
virtual void itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::SetVariance ( double  _arg)
virtual

Set/Get the variance of the Gaussian blurring for the accumulator.

◆ Simplify()

template<typename TInputPixelType , typename TOutputPixelType >
void itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::Simplify ( )

Simplify the accumulator. Performs the same iteration process as the Update() method, but finds the maximum along the curve and then removes the curve.
