Direct Known Subclasses:

PrincipalAxisLength, PrincipalAxisOrientation

public abstract class SpecificAxisBase
extends ImageMomentsBase

A feature based on one specific principal-axis as identified by image moments.

Principal axes are ordered by eigen-value, with 0 being the largest, 1 being the second-largest etc.

calculateFromAllMoments

protected double calculateFromAllMoments(ImageMoments moments)
                                  throws FeatureCalculationException

Description copied from class: ImageMomentsBase

Calculates the feature value from the ImageMoments.

Specified by:

calculateFromAllMoments in class ImageMomentsBase

Parameters:

moments - the ImageMoments to use for calculation

Returns:

the calculated feature value

Throws:

FeatureCalculationException - if the calculation fails

calculateFromSpecificMoment

protected abstract double calculateFromSpecificMoment(EigenvalueAndVector moment)
                                               throws FeatureCalculationException

Calculates the result for the specific moment identified by index.

Parameters:

moment - the EigenvalueAndVector for the specific moment

Returns:

the calculated result as a Double

Throws:

FeatureCalculationException - if the calculation fails

getIndex
