@classmethod
def from_cvat_images(cls, cvat_images): (source) ¶

Creates a CVATTaskLabels instance that describes the active schema of the given annotations.

Parameters
cvat_images	a list of `CVATImage` instances
Returns
a `CVATTaskLabels`

@classmethod
def from_cvat_tracks(cls, cvat_tracks): (source) ¶

Creates a CVATTaskLabels instance that describes the active schema of the given annotations.

Parameters
cvat_tracks	a list of `CVATTrack` instances
Returns
a `CVATTaskLabels`

@classmethod
def from_labels_dict(cls, d): (source) ¶

Creates a CVATTaskLabels instance from the <labels> tag of a CVAT annotation XML file.

Parameters
d	a dict representation of a `<labels>` tag
Returns
a `CVATTaskLabels`

@classmethod
def from_schema(cls, schema): (source) ¶

Creates a CVATTaskLabels instance from an eta.core.image.ImageLabelsSchema.

Parameters
schema	an `eta.core.image.ImageLabelsSchema`
Returns
a `CVATTaskLabels`

def __init__(self, labels=None): (source) ¶

Undocumented

def merge_task_labels(self, task_labels): (source) ¶

Merges the given CVATTaskLabels into this instance.

Parameters
task_labels	a `CVATTaskLabels`

def to_schema(self): (source) ¶

Returns an eta.core.image.ImageLabelsSchema representation of the task labels.

Note that CVAT's task labels schema does not distinguish between boxes, polylines, and keypoints, so the returned schema stores all annotations under the "objects" field.

Returns
an `eta.core.image.ImageLabelsSchema`
