xbob.db.frgc is a Python module that 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.
This database interface requires the original image database to be available at your system. In order for the database interface to work properly, you have to 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. For use at Idiap, the right directory is pre-set.
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:
a. You can download it from PyPI, or
b. You can download it in its source form from its git repository. When you download the version at the git repository, you will need to run a command to recreate the backend SQLite file required for its operation. This means that the database raw files must be installed somewhere in this case. With option 1 you can run in dummy mode and only download the raw data files for the database once you are happy with your setup.
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:
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:
extensions = mr.developer
auto-checkout = *
eggs = bob
xbob.db.frgc = git https://github.com/bioidiap/xbob.db.frgc.git
