Antispoofing cross database testing

This package contains scripts that permit to make a cross database testing in face antispoofing countermeasures in order evaluate them generalization power.

Installation

Note

If you are reading this page through our GitHub portal and not through PyPI, note the development tip of the package may not be stable or become unstable in a matter of moments.

Go to http://pypi.python.org/pypi/antispoofing.crossdatabase to download the latest stable version of this package.

There are 2 options you can follow to get this package installed and operational on your computer: you can use automatic installers like pip (or easy_install) or manually download, unpack and use zc.buildout to create a virtual work environment just for this package.

Using an automatic installer

Using pip is the easiest (shell commands are marked with a $ signal):

$ pip install antispoofing.crossdatabase

You can also do the same with easy_install:

$ easy_install antispoofing.crossdatabase

This will download and install this package plus any other required dependencies. It will also verify if the version of Bob you have installed is compatible.

This scheme works well with virtual environments by virtualenv or if you have root access to your machine. Otherwise, we recommend you use the next option.

Using zc.buildout

Download the latest version of this package from PyPI and unpack it in your working area. The installation of the toolkit itself uses buildout. You don’t need to understand its inner workings to use this package. Here is a recipe to get you started:

$ python bootstrap.py
$ ./bin/buildout

These 2 commands should download and install all non-installed dependencies and get you a fully operational test and development environment.

Note

The python shell used in the first line of the previous command set determines the python interpreter that will be used for all scripts developed inside this package. Because this package makes use of Bob, you must make sure that the bootstrap.py script is called with the same interpreter used to build Bob, or unexpected problems might occur.

If Bob is installed by the administrator of your system, it is safe to consider it uses the default python interpreter. In this case, the above 3 command lines should work as expected. If you have Bob installed somewhere else on a private directory, edit the file buildout.cfg before running ./bin/buildout. Find the section named buildout and edit or add the line prefixes to point to the directory where Bob is installed or built. For example:

[buildout]
...
prefixes=/Users/crazyfox/work/bob/build/lib

User Guide

First of all, it is necessary to be familiarized with the satellite packages: antispoofing.motion and antispoofing.lbptop. The antispoofing.lbptop satellite package generates the scores of the LBP-TOP and LBP countermeasures.

Crossdatabase test

The examples bellow show how to reproduce the performance using the inter-database protocol.

For each countermeasure trained and tuned with the Replay Attack Database, to get the performance using the test set of the Casia FASD, just type:

$ ./bin/crossdb_result_analysis.py --scores-dir <scores_replay_countermeasure_directory> -d replay -t casias_fasd:

For each countermeasure trained and tuned with the Casia FASD, to get the performance using the test set of the Replay Attack Database, just type:

$ ./bin/crossdb_result_analysis.py --scores-dir <scores_casia_countermeasure_directory> -d casia_fasd -t replay

Training all data

To get the performance using a countermeasure trained and tuned with both databases (Replay Attack Database and Casia FASD) just type:

To report the results using the Replay Attack Database:

$ ./bin/crossdb_result_analysis.py --scores-dir <scores_all_countermeasures_directory> -d all -t replay

To report the results using the Casia FASD:

$ ./bin/crossdb_result_analysis.py --scores-dir <scores_all_countermeasures_directory> -d all -t casia_fasd

Framework

For each countermeasures, to get the performance using the Score Level Fusion based Framework just type:

To report the results using the Replay Attack Database:

$ ./bin/crossdb_fusion_framework.py --scores-dir <scores_trained_with_replay> <scores_trained_with_casia> -d all -t replay --normalizer MinMaxNorm --fusion-algorithm SUM

To report the results using the Casia FASD:

$ ./bin/crossdb_fusion_framework.py --scores-dir <scores_trained_with_casia> <scores_trained_with_replay> -d all -t casia_fasd --normalizer MinMaxNorm --fusion-algorithm SUM
