All Implemented Interfaces:

Provider<FeatureList<FeatureInputStack>>

public class IntensityMoments
extends FeatureListProvider<FeatureInputStack>

Calculate various moment-related statistics about the intensity of each channel of an image.

As the features are unaware of the number of channels in a particular stack, a large number of features are created, referring to successive channels. If a feature references a channel that does not exist in a particular image, then Double.NaN will be calculated.

For each channel, the following is calculated:

1. sum (zeroth raw moment)
2. mean (first raw moment)
3. standard-deviation (square root of the variance)
4. variance (second central moment)
5. skewness (normalized third central moment)
6. kurtosis (standardized fourth central moment)
