org.anchoranalysis.plugin.image.feature.bean.object.single.moments.RatioPrincipalAxisLength
public class RatioPrincipalAxisLength
extends ImageMomentsBase
Calculates the ratio of prinicpal-axis length using Image Moments.

Specifically this is the highest-magnitude eigen-value (normalized) to second-highest (normalized) eigen-value.

See Image moment on Wikipedia for the precise calculation.

See Stack overflow post for the normalization procedure.
