The Face Recognition Grand Challenge (FRGC) ver2.0 Database

This package contains the access API and descriptions for The Face Recognition Grand Challenge (FRGC) Database in the version ver2.0. The actual raw data for the database should be downloaded from the original URL. This package only contains the Bob accessor methods to use the DB directly from python. Note that currently only the experimental protocols 2.0.1, 2.0.2, and 2.0.4 (as defined in the FRGC tests) are implemented.

Note

Since this database interface directly works with the file lists of the database directly, it requires the original image database to be available at your system. In order for the database interface to work properly, you have to specify the correct path on each usage. To avoid that, you can set the path in the Interface.frgc_database_directory() function of the xbob/db/frgc/driver.py file to your FRGC image database main directory. (Of course, you have to download the source package from git to do that, see below.) For use at Idiap, the right directory is preset.

You would normally not install this package unless you are maintaining it. What you would do instead is to tie it in at the package you need to use it. There are a few ways to achieve this:

  1. You can add this package as a requirement at the setup.py for your own satellite package or to your Buildout .cfg file, if you prefer it that way. With this method, this package gets automatically downloaded and installed on your working environment, or
  2. You can manually download and install this package using commands like easy_install or pip.

The package is available in two different distribution formats:

  1. You can download it from PyPI, or
  2. You can download it in its source form from its git repository.

You can mix and match points 1/2 and a/b above based on your requirements. Here are some examples:

Modify your setup.py and download from PyPI

That is the easiest. Edit your setup.py in your satellite package and add the following entry in the install_requires section:

install_requires=[
  ...
  "xbob.db.frgc",
],

Proceed normally with your boostrap/buildout steps and you should be all set. That means you can now import the xbob.db.frgc namespace into your scripts.

Modify your buildout.cfg and download from git

You will need to add a dependence to mr.developer to be able to install from our git repositories. Your buildout.cfg file should contain the following lines:

[buildout]
...
extensions = mr.developer
auto-checkout = *
eggs = bob
       ...
       xbob.db.frgc

[sources]
xbob.db.frgc = git https://github.com/bioidiap/xbob.db.frgc.git
