Class MarrHildreth

java.lang.Object

de.lmu.ifi.dbs.jfeaturelib.edgeDetector.MarrHildreth

All Implemented Interfaces:

Descriptor

public class MarrHildreth
extends Object
implements Descriptor

The Marr Hildreth edge detector uses the Laplacian of the Gaussian function to detect edges. Faster runtimes could by achieved by using Difference of Gaussians instead.

Constructor Detail

MarrHildreth

public MarrHildreth()

Creates Marr Hildreth edge detection with default parameters

MarrHildreth

public MarrHildreth(double deviation,
            int kernelSize,
            int times)

Creates Marr Hildreth edge detection

Parameters:

deviation -

Method Detail

process

public void process()

supports

public EnumSet<Descriptor.Supports> supports()

Defines the capability of the algorithm.

Specified by:

supports in interface Descriptor

Returns:

the set of supported capabilities.

PlugInFilter, supports()

run

public void run(ij.process.ImageProcessor ip)

Starts the canny edge detection.

Specified by:

run in interface Descriptor

Parameters:

ip - ImageProcessor of the source image

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Description copied from interface: Descriptor

Adds a change listener to this descriptor. The descriptor might fire status change events which can be used to track the progress. Keep in mind that no implementation is forced to fire any events at all.

Specified by:

addPropertyChangeListener in interface Descriptor

getDeviation

public double getDeviation()

Returns:

deviation value

setDeviation

public void setDeviation(double deviation)

Sets deviation

Parameters:

deviation -

getKernelSize

public int getKernelSize()

Returns:

kernel size

setKernelSize

public void setKernelSize(int kernelSize)

Sets size of kernel

Parameters:

kernelSize -

getIterations

public int getIterations()

Returns:

amount of iterations

setIterations

public void setIterations(int times)

Sets number of iterations

Parameters:

times -
