CUHK Face Sketch Database (CUFS)

bob.db.cuhk_cufs.get_config()[source]

Returns a string containing the configuration information.

class bob.db.cuhk_cufs.Annotation(file_id, x, y, index=0)[source]

Bases: sqlalchemy.ext.declarative.api.Base

The CUHK-CUFS provides 35 coordinates. To model this coordinates this table was built. The columns are the following:

  • Annotation.id
  • x
  • y
file_id
x
y
index
class bob.db.cuhk_cufs.Client(id, gender, original_id, original_database)[source]

Bases: sqlalchemy.ext.declarative.api.Base

annotations(file, annotation_type='eyes_center')[source]

This function returns the annotations for the given file id as a dictionary.

Parameters

file: bob.db.base.File
The File object you want to retrieve the annotations for,
Return
A dictionary of annotations, for face images usually something like {‘leye’:(le_y,le_x), ‘reye’:(re_y,re_x), …}, or None if there are no annotations for the given file ID (which is the case in this base class implementation).
clients(protocol=None, groups=None)[source]
groups(protocol=None, **kwargs)[source]

This function returns the list of groups for this database.

modalities
modality_separator
model_ids(protocol=None, groups=None)[source]
objects(groups=None, protocol=None, purposes=None, model_ids=None, modality=None, **kwargs)[source]

This function returns lists of File objects, which fulfill the given restrictions.

original_file_name(file, check_existence=True)[source]

This function returns the original file name for the given File object.

Parameters

file: File
The File objects for which the file name should be retrieved
check_existence: bool
Check if the original file exists? IGNORED: ALWAYS CHECK

purposes()[source]
tclients(protocol=None)[source]

Returns a set of T-Norm clients for the specific query by the user.

tmodel_ids(groups=None, protocol=None, **kwargs)[source]

This function returns the ids of the T-Norm models of the given groups for the given protocol.

tobjects(protocol=None, model_ids=None, groups=None)[source]
