This package contains scripts that permit to make a cross database testing in face antispoofing countermeasures in order evaluate them generalization power.
If you use this package and/or its results, please cite the following publications:

Installation
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.
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
