In BriefCam, the Face Recognition filter includes three tolerance levels to help you fine-tune your results.

The available values for the Tolerance field are:

  • Strict – With this tolerance level, there is a higher FRR and lower FAR. This means that you will see mainly thumbnails of the same matching object. However, some of the correct matches might be missed. False positives might be received, but less than with the Normal tolerance level.

  • Normal (default) – With this tolerance level you will see the majority of the appearances of the same object, but you may also see a few wrong matches (false positives).

  • Loose – With this tolerance level, there is a lower FRR and higher FAR. This means that you will see all thumbnails of the same object, but you will also see quite a few wrong matches.

In addition, as the number of objects in the case grows, the number of false matches might increase.

Note

BriefCam allows you to sort the results using “Relevance” so you can see matches with the highest matching score (i.e. confidence) ranked first.
