Method Detail

getFeatures

List<double[]> getFeatures()

Returns the values of the descriptor as a double array. The semantics of the according values should be explained in the JavaDocs of the implementing class. If features are not (yet) computed, an empty listis returned.

Returns:

list of feature vectors

getDescription

String getDescription()

Returns a short plain Text description about the Descriptor and the semantics of the double array obtained from getFeatures(). May return null if no description is implemented - even though this should be avoided by any means.

Returns:

semantic description of getFeatures or null.

setProperties

void setProperties(LibProperties properties)
                   throws IOException

Injects the properties class that can be used to retrieve several properties.

Throws:

IOException - if something went wrong
