Rectangles enable object detection.
Architectures such as R-CNN, YOLO and SSD support rectangles (also known as bounding boxes) as input. Some use cases include detecting people in photos, buildings in satellite imagery, and gunshots in audio spectrograms.
This is useful for having classes associated with higher level instances. Example: drawing rectangles around birds for object detection, but having a class for types of bird within the rectangle (Duck, Geese, etc...).

The Rectangle schema element creates an array of objects with data consisting of minimum and maximum XY coordinates. These minimum and maximum values define the boundaries of the rectangle. The XY coordinate values are relative (0.0 to 1.0) to width and height respectively.
