Class IFftComplex32

java.lang.Object
  jjil.core.PipelineStage
      jjil.algorithm.IFftComplex32

public class IFftComplex32
extends PipelineStage

Computes the inverse FFT of the input Complex32Image. The output is a Gray8Image, which is the magnitude of the inverse FFT. The output can be scaled so the maximum and minimum values of the magnitude are mapped to Byte.MAX_VALUE and Byte.MIN_VALUE.
