public abstract class FeatureCalculatorLBPJFeatureLib
extends FeatureCalculator

Abstract super class for LBP operators building on the JFeatureLib.

Operators implementing LBPs based on the JFeatureLib are expected to support neighborhoods with a given radius and number of neighboring pixels. In addition they are expected to either return LBP code histograms for each pixel in an image or for the image as a whole.
