Each "stuff" class will be converted to a single Polyline that may contain multiple disjoint shapes capturing the class.

Each "thing" class will result in one Polyline instance per connected region of that class.

Parameters

• mask_targets (None) – a dict mapping integer pixel values (2D masks) or RGB hex strings (3D masks) to label strings defining which classes to generate detections for. If omitted, all labels are assigned to their pixel values

• mask_types ("stuff") –

STRICT = False

clean()

Hook for doing document level data cleaning (usually validation or assignment) before validation is run.

Any ValidationError raised by this method will not be associated with a particular field; it will have a special-case association with the field defined by NON_FIELD_ERRORS.

Parameters

name – the attribute name

Raises

AttributeError – if the attribute does not exist

fancy_repr(class_name=None, select_fields=None, exclude_fields=None, **kwargs)

Generates a customizable string representation of the document.

Parameters

• class_name (None) – optional class name to use

• select_fields (None) – iterable of field names to restrict to

• exclude_fields (None) – iterable of field names to exclude

• **kwargs – additional key-value pairs to include in the string representation

Returns

a string representation of the document

property field_names

An ordered tuple of the public fields of this document.

field_to_mongo(field_name)

field_to_python(field_name, value)

classmethod from_dict(d, extended=False)

Returns

a SerializableDocument

get_attribute_value(name, default=<fiftyone.core.labels._NoDefault object>)
