Bob 2.0 implementation of the biometrics evaluation metrics for anti-spoofing methods
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.
|Endpoint Name||Data Format||Nature|
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.
Parameters allow users to change the configuration of an algorithm when scheduling an experiment
|n_bins_negatives||Number of histogram bins for negative scores||uint32||100|
|n_bins_positives||Number of histogram bins for positive scores||uint32||20|
The code for this algorithm in Python
The ruler at 80 columns indicate suggested POSIX line breaks (for readability).
The editor will automatically enlarge to accomodate the entirety of your input

An algorithm that implements standard metrics for antispoofing evaluation.
Specifically, it outputs, for the development set, the following quantities:
And for the test set:
This table shows the number of times this algorithm has been successfully run using the given environment. Note this does not provide sufficient information to evaluate if the algorithm will run when submitted to different conditions.
