Ellipses

Given an ellipse entry in params.geometries, Scale will annotate your image or video with ellipses and return the extremal points of the ellipses. The ellipses may be rotated relative to the X and Y axes.

Parameters

KeyTypeDescription
objects_to_annotatearrayA list of string or LabelDescription objects.

Response Fields

KeyTypeDescription
uuidstringA computer-generated unique identifier for this annotation.

In video annotation tasks, this can be used to track the same object across frames.
typestringString to indicate geometry type: ellipse
labelstringThe label of this annotation, chosen from the objects_to_annotate array for its geometry. In video annotation tasks, any annotation objects with the same uuid will have the same label across all frames.
attributesobjectSee the Annotation Attributes section for more details about the attributes response field.
verticesarrayA list of Vertex objects of length 4 describing the extremal vertices of the ellipse
