==============
 User's Guide
==============

This package contains the access API and descriptions for the `AT&T`_ database of faces, which is formerly known as the ORL database.
The actual raw data for the database should be downloaded from the original URL.
If you don't download the data yourself, it will automatically be downloaded to a temporary directory each time you create a :py:class:`bob.db.atnt.Database` object.

This package only contains the Bob_ accessor methods to use the DB directly from python, using a single self-designed evaluation protocol.


The Database Interface
----------------------

The :py:class:`bob.db.atnt.Database` complies with the standard biometric verification database as described in :ref:`commons`, implementing the interface :py:class:`bob.db.verification.utils.Database`.
