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.

Member Function Documentation

◆ CreateAnother()

template<typename TInputPixelType , typename TOutputPixelType >
virtual::itk::LightObject::Pointer itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::CreateAnother ( ) const
virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

◆ EnlargeOutputRequestedRegion()

template<typename TInputPixelType , typename TOutputPixelType >
void itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::EnlargeOutputRequestedRegion ( DataObject *  output)
overrideprotectedvirtual

HoughTransform2DLinesImageFilter must produce the entire output.

Reimplemented from itk::ProcessObject.

◆ GenerateData()

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

Method for evaluating the implicit function over the image.

Reimplemented from itk::ProcessObject.

◆ GenerateInputRequestedRegion()

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

HoughTransform2DLinesImageFilter needs the entire input. Therefore it must provide an implementation GenerateInputRequestedRegion().

See also
ProcessObject::GenerateInputRequestedRegion().

Reimplemented from itk::ProcessObject.

◆ GenerateOutputInformation()

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

HoughTransform2DLinesImageFilter's output is the accumulator array. The size of the output is a function of the size of the input and the AngleAxisSize. Since this output is a different size than the input, it must provide an implementation of GenerateOutputInformation.

See also
ProcessObject::GenerateOutputRequestedRegion()

Reimplemented from itk::ProcessObject.

◆ GetAngleResolution()

template<typename TInputPixelType , typename TOutputPixelType >
virtual double itk::HoughTransform2DLinesImageFilter< TInputPixelType, TOutputPixelType >::GetAngleResolution ( ) const
