Class IntegralImg<R extends net.imglib2.type.numeric.NumericType<R>,T extends net.imglib2.type.numeric.NumericType<T> & net.imglib2.type.NativeType<T>>

java.lang.Object

net.imglib2.algorithm.integral.IntegralImg<R,T>

Type Parameters:

R - The type of the input image.

T - The type of the integral image.

All Implemented Interfaces:

Algorithm, OutputAlgorithm<net.imglib2.img.Img<T>>

Direct Known Subclasses:

IntegralImgDouble, IntegralImgLong

public class IntegralImg<R extends net.imglib2.type.numeric.NumericType<R>,T extends net.imglib2.type.numeric.NumericType<T> & net.imglib2.type.NativeType<T>>
extends Object
implements OutputAlgorithm<net.imglib2.img.Img<T>>

n-dimensional integral image that stores sums using type <T>. Care must be taken that sums do not overflow the capacity of type <T>. The integral image will be one pixel larger in each dimension as for easy computation of sums it has to contain "zeros" at the beginning of each dimension The Converter defines howto convert from Type <R> to <T>. Sums are done with the precision of <T> and then set to the integral image type, which may crop the values according to the type's capabilities.
