itk::HoughTransform2DCirclesImageFilter< TInputPixelType, TOutputPixelType, TRadiusPixelType > Class Template Reference

#include <itkHoughTransform2DCirclesImageFilter.h>

Detailed Description

template<typename TInputPixelType, typename TOutputPixelType, typename TRadiusPixelType>
class itk::HoughTransform2DCirclesImageFilter< TInputPixelType, TOutputPixelType, TRadiusPixelType >

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

This filter derives from the base class ImageToImageFilter. The input is an image, and all pixels above some threshold are those we want to consider during the process.

This filter produces two output: 1) The accumulator array, which represents probability of centers. 2) The array or radii, which has the radius value at each coordinate point.

When the filter finds a "correct" point, it computes the gradient at this point and draws a regular narrow-banded circle using the minimum and maximum radius given by the user, and fills in the array of radii. The SweepAngle value can be adjusted to improve the segmentation.

The filter will detect ring-shaped objects in the image, but it also finds discs. For a disc to be found, the intensity values within the disc must be higher than the surrounding of the disc.

TOutputPixelType is the pixel type of the accumulator image. An unsigned integer type (like 'unsigned long') is usually the best choice for this pixel type.

TRadiusPixelType is the pixel type of the radius image. A floating point type is recommended, as the estimation of the radius involves floating point calculations. Usually, 'double' is the best choice for this pixel type.
