Detailed Description

template<typename TInputImage, typename TOutputImage = TInputImage>
class iAEntropyImageFilter< TInputImage, TOutputImage >

Calculates the pixelwise entropy out of a collection of input images.

INPUTS

All inputs to this filter must be floating point images representing a distribution (i.e. their sum should be 1) Input volumes must all contain the same size RequestedRegions.

OUTPUTS

The filter produces a single output volume. Each output pixel contains the entropy of the given pixel over all input volumes. Higher values indicate higher "uncertainty", i.e. an equal distribution of probabilities; lower values indicate that less evenly distributed probabilities; a value of 0 indicates that the probability of one input is 1, while the others are all 0.

PARAMETERS

Normalize whether the output entropy should be normalized to the interval [0..1]
