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.
