Standard metrics for biometric system evaluation

Forked from tutorial/postperf/1

This algorithm is a legacy one. The API has changed since its implementation. New versions and forks will need to be updated.
This algorithm is an analyzer. It can only be used on analysis blocks.

Algorithms have at least one input and one output. All algorithm endpoints are organized in groups. Groups are used by the platform to indicate which inputs and outputs are synchronized together. The first group is automatically synchronized with the channel defined by the block in which the algorithm is deployed.

Group: main

Analyzers may produce any number of results. Once experiments using this analyzer are done, you may display the results or filter experiments using criteria based on them.

An algorithm that implements standard metrics for biometric system evaluation.

Specifically, it returns:

  • eer: the equal error rate (EER)
  • far: the false acceptance rate (FAR)
  • frr: the false rejection rate (FRR)
  • number_of_positives: the number of positive (genuine) trials
  • number_of_negatives: the number of negative (impostor) trials
  • threshold: the threshold at the equal error rate
  • roc: the receiver operating characteristic (ROC) curve according to the biometrics standard ISO/IEC 19795-1:2006(E)

This implementation relies on the 'measure' package from the Bob library.
