Class Eccentricity

java.lang.Object

de.lmu.ifi.dbs.jfeaturelib.features.AbstractFeatureDescriptor

de.lmu.ifi.dbs.jfeaturelib.shapeFeatures.Eccentricity

All Implemented Interfaces:

Descriptor, FeatureDescriptor

public class Eccentricity
extends AbstractFeatureDescriptor

Computes the ratio of the length of the longest chord of the shape to the longest chord perpendicular to it according to "Bryan S. Morse (2000): Lecture 9: Shape Description (Regions), Brigham Young University, Available from: http://homepages.inf.ed.ac.uk/rbf/CVonline/LOCAL_COPIES/MORSE/region-props-and-moments.pdf".

Constructor Detail

Eccentricity

public Eccentricity()

Method Detail

getEccentricity

public double getEccentricity()

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.

supports

public EnumSet<Descriptor.Supports> supports()

Description copied from interface: Descriptor

Determine the capabilities of this algorithm.

Specified by:

supports in interface Descriptor

Overrides:

supports in class AbstractFeatureDescriptor

Returns:

the set of supported capabilities.

getDescription

public String getDescription()

Description copied from interface: FeatureDescriptor

Returns a short plain Text description about the Descriptor and the semantics of the double array obtained from FeatureDescriptor.getFeatures(). May return null if no description is implemented - even though this should be avoided by any means.

Returns:

semantic description of getFeatures or null.
