Package: xbob.db.gbu
This package contains the access API and descriptions forThe Good, The Bad, and The Ugly Database.
The actual raw data for the database should be downloaded from the original URL.
This package only contains theBobaccessor methods to use the DB directly from python.
Note that the default protocolsGood,Bad, andUglyas defined in the URL above will be respected.Downloading this packageYou 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 touseit.
There are a few ways to achieve this:You can add this package as a requirement at thesetup.pyfor your ownsatellite packageor to your Buildout.cfgfile, if you prefer it that way.
With this method, this package gets automatically downloaded and installed on your working environment, orYou can manually download and install this package using commands likeeasy_installorpip.The package is available in two different distribution formats:You can download it fromPyPI, orYou can download it in its source form fromits 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 option1you can run indummymode 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 PyPIThat is the easiest.
Edit yoursetup.pyin your satellite package and add the following entry in theinstall_requiressection:install_requires=[
  ...
  "xbob.db.gbu",
],Proceed normally with yourboostrap/buildoutsteps and you should be all set.
That means you can now import thexbob.db.gbunamespace into your scripts.Modify your buildout.cfg and download from gitYou will need to add a dependence tomr.developerto be able to install from our git repositories.
Yourbuildout.cfgfile should contain the following lines:[buildout]
...
extensions = mr.developer
auto-checkout = *
eggs = bob
       ...
       xbob.db.gbu

...Installation of the original image databaseTo be able to use this database, please have a look at the NIST webpage:http://www.nist.gov/itl/iad/ig/focs.cfmand download: the Multiple Biometric Grand Challenge (MBGC)-V1 image database if you do not have a copy of it yet.Unfortunately, the directory structure in this image database has changed.
If you have an older version of it, and the test:$ bob_dbmanage.py gbu checkfiles --directory <YOUR_PATH_TO_MBGC-V1>fails (i.e. reports missing files), you have two possible options:Download the GBU-sigsets.zip file fromhttps://github.com/bioidiap/xbob.db.gbu/downloads, extract the zip to a directory of your choice and call:$ bob_dbmanage.py gbu create --recreate --list-directory <YOUR_PATH_TO_THE_XML_LISTS> --rescan-image-directory <YOUR_PATH_TO_MBGC-V1>(you might need root access to recreate the database)Copy (or link) the images of the MBGC-V1 database into a directory that has the required directory structure by calling:$ bob_dbmanage.py gbu copy-image-files --soft-link --original-image-directory <YOUR_PATH_TO_MBGC-V1> --new-image-directory <NEW_IMAGE_PATH_TO_BE_CREATED>To be sure that the procedure succeeded, please call:$ bob_dbmanage.py gbu checkfiles --directory <YOUR_PATH_TO_MBGC-V1>or:$ bob_dbmanage.py gbu checkfiles --directory <NEW_IMAGE_PATH_TO_BE_CREATED>afterwards. If this fails again, your copy of the MBGC-V1 database is corrupted, and you might consider to get a new copy of it.NoteThe lists fromhttps://github.com/bioidiap/xbob.db.gbu/downloadscontains the file lists as provided by the CSU Face Recognition Resources, seehttp://www.cs.colostate.edu/facerec/algorithms/baselines2011.php.
In these files, the directory structure is adapted to our (the latest?) version of the MBGC-V1 database.
