public class ComputeLocalNiblackThresholdIntegral<T extends RealType<T>,U extends RealType<U>>
extends Object
implements Computers.Arity4<RectangleNeighborhood<? extends Composite<U>>,T,Double,Double,BitType>

Niblack's local thresholding algorithm.

This implementation improves execution speed by using integral images for the computations of mean and standard deviation in the local windows. A significant improvement can be observed for increased window sizes ( span > 10). It operates on RandomAccessibleIntervals of RealType, i.e. explicit conversion to an integral image is not required.
