Class LocalLBPHistogram

java.lang.Object

org.openimaj.image.processing.face.feature.LocalLBPHistogram

All Implemented Interfaces:

FeatureVectorProvider<FloatFV>, FacialFeature, ReadableBinary, ReadWriteableBinary, WriteableBinary

public class LocalLBPHistogram
extends Object
implements FacialFeature, FeatureVectorProvider<FloatFV>

A FacialFeature built from decomposing the face image into (non-overlapping) blocks and building histograms of the ExtendedLocalBinaryPatterns for each block and then concatenating to form the final feature.
