Image labeling task feature.

Values: FEATURE_UNSPECIFIED (0):

CLASSIFICATION (1):
    Label whole image with one or more of labels.
BOUNDING_BOX (2):
    Label image with bounding boxes for labels.
ORIENTED_BOUNDING_BOX (6):
    Label oriented bounding box. The box does not
    have to be parallel to horizontal line.
BOUNDING_POLY (3):
    Label images with bounding poly. A bounding
    poly is a plane figure that is bounded by a
    finite chain of straight line segments closing
    in a loop.
POLYLINE (4):
    Label images with polyline. Polyline is
    formed by connected line segments which are not
    in closed form.
SEGMENTATION (5):
    Label images with segmentation. Segmentation
    is different from bounding poly since it is more
    fine-grained, pixel level annotation.
