Class MinMaxAmplitudes

java.lang.Object
  marf.Storage.StorageManager
      marf.FeatureExtraction.FeatureExtraction
          marf.FeatureExtraction.MinMaxAmplitudes.MinMaxAmplitudes

All Implemented Interfaces:: marf.FeatureExtraction.IFeatureExtraction, marf.Storage.IStorageManager, java.io.Serializable

public class MinMaxAmplitudes
extends marf.FeatureExtraction.FeatureExtraction

Min/Max Amplitudes.

Extracts N minimum and X maximum amplitudes from a sample as features. If incoming sample array's length is less than N + X, it is adjusted to be N + X long with the length/2 value repeated N + X - length times.

TODO: needs improvement to select different amplitudes as we don't want 20 the same maximums or minimus if others are avaible.

Since:: 0.3.0
Version:: $Revision: 1.12 $
