class bob.db.mobio.Database(original_directory=None, original_extension=None, annotation_directory=None, annotation_extension='.pos')

Bases: bob.db.base.SQLiteDatabase

The dataset class opens and maintains a connection opened to the Database.

It provides many different ways to probe for the characteristics of the data and for the data itself inside the database.

groups(protocol=None)

Returns the names of all registered groups

genders()

Returns the list of genders

subworld_names()

Returns all registered subworld names

subworlds()

Returns the list of subworlds

has_subworld(name)

Tells if a certain subworld is available

clients(protocol=None, groups=None, subworld=None, gender=None)

Returns a list of Clients for the specific query by the user.

Keyword Parameters:

protocol

One of the MOBIO protocols (‘mobile0-male’, ‘mobile0-female’, ‘mobile1-male’, ‘mobile1-female’, ‘laptop1-male’, ‘laptop1-female’, ‘laptop_mobile1-male’, ‘laptop_mobile1-female’) ‘male’and ‘female’ are aliases for ‘mobile0-male’ and ‘mobile0-female’, respectively.

groups

The groups to which the clients belong (‘dev’, ‘eval’, ‘world’) Please note that world data are protocol/gender independent

subworld

Specify a split of the world data (‘onethird’, ‘twothirds’, ‘twothirds-subsampled’) In order to be considered, ‘world’ should be in groups and only one split should be specified.

gender

The gender to consider (‘male’, ‘female’)

Returns: A list containing all the clients which have the given properties.

has_client_id(id)

Returns True if we have a client with a certain integer identifier

client(id)

Returns the Client object in the database given a certain id. Raises an error if that does not exist.
