Class Roberts

java.lang.Object

de.lmu.ifi.dbs.jfeaturelib.edgeDetector.Roberts

All Implemented Interfaces:

Descriptor

public class Roberts
extends Object
implements Descriptor

Simple implementation of the Roberts(Cross)-Operator. The Roberts-Cross-Operator uses just 2x2 matrices instead of the alsmost standard odd-sized kenrels. For sake of simplicity (and in order to conveniently use imageJ's convolve method), the following 3x3 matrix is used which should produce the same result as the 2x2 matrix (just a bit more inefficient):

 0  0  0
 0  1  1
 0 -1 -1

Method Detail

supports

public EnumSet<Descriptor.Supports> supports()

Description copied from interface: Descriptor

Determine the capabilities of this algorithm.

Specified by:

supports in interface Descriptor

Returns:

the set of supported capabilities.

run

public void run(ij.process.ImageProcessor ip)

Description copied from interface: Descriptor

Start processing of this algorithm on the given image processor. Keep in mind that if the imageProcessor is changed, Supports.NoChanges must not be set. This is also the case even if only ImageProcessor.snapshot() is used.

Specified by:

run in interface Descriptor

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
