Feature Extraction

Long Description

This application validates or unvalidate the studied samples using the Dempster-Shafer theory.

Parameters

• Input Vector Data (in): Input vector data to validate

• Descriptors model filename (descmod): Fuzzy descriptors model (xml file)

• Belief Support (belsup): Dempster Shafer study hypothesis to compute belief

• Plausibility Support (plasup): Dempster Shafer study hypothesis to compute plausibility

• Criterion (cri): Dempster Shafer criterion (by default (belief+plausibility)/2)

• Criterion threshold (thd): Criterion threshold (default 0.5)

• Output Vector Data (out): Output VectorData containing only the validated samples

• Load otb application from xml file (inxml): Load otb application from xml file

• Save otb application to xml file (outxml): Save otb application to xml file

Limitations

None.
