public double[] extractFeature(double[] samples, double sampling_rate, double[][] other_feature_values) throws java.lang.Exception
In the case of this feature, the sampling_rate and other_feature_values parameters are ignored.
extractFeature
in class FeatureExtractor
samples
- The samples to extract the feature from.sampling_rate
- The sampling rate that the samples are
encoded with.other_feature_values
- The values of other features that are
needed to calculate this value. The
order and offsets of these features
must be the same as those returned by
this class's getDependencies and
getDependencyOffsets methods respectively.
The first indice indicates the feature/window
and the second indicates the value.
