Class HoughTransformOp

java.lang.Object
  org.generation5.vision.HoughTransformOp

Direct Known Subclasses:

LineHoughTransformOp

public abstract class HoughTransformOp

extends java.lang.Object

This abstract class is for subclasses to implement different derivates of Hough Transforms. Note that as this is more of an operation, not a filter, this class does not implement the Filter interface.

Constructor Summary

HoughTransformOp()
Creates a new instance of HoughTransform

Method Summary

abstract java.awt.image.BufferedImage	getAccumulatorImage() Return a BufferedImage of the accumulator.
abstract java.awt.image.BufferedImage	getSuperimposed(java.awt.image.BufferedImage img, double threshold) Return an image of the Hough Transform results superimposed on the input image.
abstract void	run(java.awt.image.BufferedImage img) Run the Hough transform on the input image.

Constructor Detail

HoughTransformOp

public HoughTransformOp()

Creates a new instance of HoughTransform

Method Detail

run

public abstract void run(java.awt.image.BufferedImage img)

Run the Hough transform on the input image.

Parameters:

img - the input image.

getAccumulatorImage

public abstract java.awt.image.BufferedImage getAccumulatorImage()

Return a BufferedImage of the accumulator. How this is implemented is up to the programmer, since accumulators can be multidimensional.

Returns:

the accumulator image.

getSuperimposed

public abstract java.awt.image.BufferedImage getSuperimposed(java.awt.image.BufferedImage img,
                                                             double threshold)

Return an image of the Hough Transform results superimposed on the input image.

Parameters:

img - the input image.

threshold - the accumulator threshold.

Returns:

the superimposed image.
