CASME2 Database

This is the Bob database entry for the AR face database.

class bob.db.casme2.Database(original_directory=None, original_extension='.ppm')

Bases: bob.db.base.SQLiteDatabase

The database 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

clients(protocol=None, groups=None)

Returns a list of Client objects for the specific query by the user.

Keyword Parameters:

groups

Ignored

protocol

Ignored since clients are identical for all protocols.

Returns: A list containing all the Client objects which have the desired properties.

client_ids(groups=None, genders=None, protocol=None)

Returns a list of client ids for the specific query by the user.

Keyword Parameters:

groups

One or several groups to which the models belong (‘world’, ‘dev’, ‘eval’). If not specified, all groups are returned.

protocol

Ignored since clients are identical for all protocols.

Returns: A list containing all the client ids which have the desired properties.

model_ids(groups=None, genders=None, protocol=None)

Returns a list of client ids for the specific query by the user.

Keyword Parameters:

groups

One or several groups to which the models belong (‘world’, ‘dev’, ‘eval’). If not specified, all groups are returned.

protocol

Ignored since clients are identical for all protocols.

Returns: A list containing all the client ids which have the desired properties.

get_client_id_from_file_id(file_id, **kwargs)

Returns the client_id (real client id) attached to the given file_id

Keyword Parameters:

file_id

The file_id to consider

Returns: The client_id attached to the given file_id

get_client_id_from_model_id(model_id, **kwargs)

Returns the client_id attached to the given model_id

Keyword Parameters:

model_id

The model id to consider

Returns: The client_id attached to the given model_id

objects(protocol=None, model_ids=None, emotions=None, purposes=None, groups=None)

Using the specified restrictions, this function returns a list of File objects.

Keyword Parameters:

protocol

CASME2 protocols.

model_ids

If given (as a list of model id’s or a single one), only the files belonging to the specified model id is returned.

emotions

One or several emotions from - If not specified, objects with all expressions emotions returned.

purpose

The purpose of the Object (Train or Test)

annotations(file_id)

Returns the annotations for the image with the given file id.

Keyword Parameters:

file

The File object to retrieve the annotations for.

Returns: the action units for the given file

class bob.db.casme2.File(client_id, path, emotion, onset, apex, offset)

Bases: sqlalchemy.ext.declarative.api.Base, bob.db.base.File

NOTE:this interface is the variant of the CASME2 database which does not use the video files, but rather the ones converted into frames of images. (i.e. the ones in the “CROPPED” folder). As such, this folder is supposed to be an abstract representation of the video file - in this case, its a fodler containing the video frames.

This is represent the video file directory containing the frames. * the emotions (‘happiness’, ‘repression’, ‘disgust’, ‘surprise’, ‘sadness’, ‘others’) for the client * the client id, in this case, each file is a frame in the video

emotion_choices = ('happiness', 'repression', 'disgust', 'surprise', 'sadness', 'fear', 'others')

class bob.db.casme2.Client(id)
