public double[] extractFeature(double[] samples, double sampling_rate, double[][] other_feature_values) throws java.lang.Exception
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.
java.lang.Exception
- Throws an informative exception if the feature cannot be
calculated.public void setNumberDimensions(int n) throws java.lang.Exception
n
- number of coeffecients to be calculated.
java.lang.Exception
- thrown if less than 1 feature is to be calculated.public java.lang.String getElement(int index) throws java.lang.Exception
getElement
in class FeatureExtractor
index
- which of AreaMoment's attributes should be edited.
java.lang.Exception
public void setElement(int index, java.lang.String value) throws java.lang.Exception
setElement
in class FeatureExtractor
index
- attribute to be setvalue
- new value of the attribute
